Even though the Samsung Galaxy S24 Ultra is now in the wild, the Samsung Galaxy S23 Ultra still packs a punch. For those who have one, it should last for many years—assuming you protect it with a case.
The Galaxy S23 Ultra isn't a cheap device, starting at a sky-high $1,200 price. If you're looking to buy one, or are currently using Samsung's big and beautiful smartphone, then you probably want to protect your investment. When kept safe, it's got the power to last. Samsung has also promised to update it all the way to Android 17, making it a smartphone you can use for years. But to keep it safe, some protection is needed. Here are the best Samsung Galaxy S23 Ultra cases available today.
Ringke Fusion-X Case
The best lanyard Galaxy S23 Ultra case
- Great value
- Unique look
- Strong protection
- Style may not be for everyone
Want a case with a design you're unlikely to find anywhere else? Ringke's Fusion-X is a classic of the accessory world, with a unique style that doesn't skimp on protection. It's a dual-layer case, meaning it uses two materials in its build, giving it the strength of a soft, absorbent TPU frame alongside a rigid, scratch-resistant polycarbonate backplate. This combo means it protects equally well against drops, bumps, scratches, and dirt. The slim build also means it also won't block wireless charging and can be used with a screen protector.
Ringke's real magic, though? You'll find that in the bottom corners of the case — a pair of QuikCatch lanyard attachment points. These points are compatible with any form of lanyard (from wrist straps to shoulder straps) and mean you can be sure of drop-proofing your smartphone. While lanyards can be cumbersome when shoved into pockets, if you're using your phone to take lots of pictures, the added security of a lanyard is very much appreciated.
UAG Monarch Kevlar Case
The best kevlar Galaxy S23 Ultra case
- Excellent all-around protection
- Cool sci-fi design
- Lightweight
- Extremely expensive
Urban Armor Gear may have a grandiose name, but it holds up to scrutiny when it produces cases like this. The UAG Monarch Kevlar includes a lot of what makes UAG's cases excellent, like the five layers of protective materials, paired with a lightweight build that doesn't weigh down your phone and doesn't add extra bulk. But the key to this particular case is the addition of industry-leading DuPont Kevlar Material. It's tested up to an impressive 20 feet for drop protection, and it meets military standards for protection as a result. Despite all that protection, it doesn't block wireless charging, and the raised bezels mean your phone won't rest directly on surfaces.
The downside? The price. UAG is a premium seller, and this is an ultra-premium case. The high price is for a truly quality product, and it reflects the similar status of your smartphone.
Ghostek Nautical Case
The best adventure Galaxy S23 Ultra case
- Protection for the most adventurous
- Drop protection up to 12 feet
- Built in screen protection
- On the more expensive side
Ghostek's Nautical case started as Ghostek's most comprehensive waterproof case, but it's evolved into so much more than that. If you're the adventurous sort, then Ghostek's Nautical case is the case for you.
It completely seals your S23 Ultra away, protecting against water, dirt, dust, snow, sand, and shocks and drops too. As such, it's as home in six feet of water as it is on top of a mountain, and the built-in screen protector also keeps dirt, dust, and scratches away from your display too. It's on the more expensive side for sure, but it also offers 12 feet of drop protection and a clear design that doesn't overly distract from your beautiful Galaxy S23 Ultra. A great all-around adventure case for those who love a life spent outdoors.
OtterBox Defender Series Case
The best belt clip Galaxy S23 Ultra case
- Great OtterBox protection
- Versatile accessories
- Kickstand
- Adds bulk
- Expensive
You can't get a much more prestigious case maker than OtterBox, and the Defender Series is one of its most notable covers. It's a multi-layer case, being made from a rubber slipcover, a polycarbonate shell, and a polycarbonate holster as a final, optional extra. The holster includes a belt clip that also doubles as a kickstand, giving it some extra versatility. It's extremely drop-safe, having been tested up to four times as many drops as needed for military standards, and it has some decent eco-standards, too, as it's made of 50% recycled material.
The only real downside is the cost. But, if you're happy to keep an eye out for sales, you can often grab this case at a good discount, as OtterBox is one of the bigger names around and a real deal magnet.
Tech21 Evo Sparkle Case
The best sparkly Galaxy S23 Ultra case
- Stylish
- Lightweight and clear
- Excellent protection
- Expensive for a simple case
Most cases commit a smartphone sin — they cover up your smartphone's gorgeous design. Not so with Tech21's Evo Sparkle. The clear material means your S23 Ultra can shine through, while the addition of the sparkly lines adds some extra flair to set off your phone's look and mark it as your own. The Evo Sparkle isn't all beauty and no brawn, too. The TPU and FlexShock blend offers 12 feet of drop protection and scratch protection and also has anti-yellowing to stop the case from yellowing as it ages.
It's expensive for a relatively simple case, though. This price often gets you a case with far more rugged protection or a case with more versatility, like a wallet case, and it's a lot for what is essentially a style case. However, it does have some impressive protective qualities for a style-focused case, so we're happy to say the money is worthwhile.
Spigen Ultra Hybrid with MagSafe
The best MagSafe Galaxy S23 Ultra case
- Clear to show off phone color
- Slim profile
- Durable protection
- MagSafe compatibility
- Affordable
- May be too minimal for some
Are you jealous of your iPhone friends who use those cool MagSafe accessories? This clear Spigen case gives you MagSafe compatibility without having to get an iPhone! With the Spigen Ultra Hybrid, you get a clear, protective case with a MagSafe-compatible magnetic ring, allowing you to use many existing MagSafe accessories with your S23 Ultra.
The clear color also lets you show off your chosen S23 Ultra color. If you got the exclusive Sky Blue or red colors from Samsung, then you’ll definitely make heads turn! The case also comes with raised edges to protect the screen and cameras, and has tactile buttons and air-cushion technology to absorb shock.
Peel Super Thin Case
The best slim Galaxy S23 Ultra case
- The absolute minimal option
- Like it's not even there
- Offers basic protection
- Expensive
- Not much protection
You won't get much protection from this case, but if you want something that's close to the thinnest possible case without crossing into being a skin, well, you've found it. Peel's cases are renowned for being the thinnest you can find, adding a barely-there TPU surface that adds protection against dirt and minor scratches, while being so thin you can see straight through it. It's the choice for minimalists and those who want to celebrate their phone's look. It's expensive for what it is, though, and it really won't offer much more than very basic protection, so keep that in mind if you plan on taking your phone out into some more challenging environments.
Temdan Full Body Waterproof Case
The best waterproof Galaxy S23 Ultra case
- Waterproof protection
- Built-in screen and camera protector
- Military grade drop protection
- Easy installation
- Bulky and cumbersome design
Plan to take your Samsung Galaxy S23 Ultra for a swim? Then you need the Temdan Full Body Waterproof Case. This case has an IP68 waterproof rating, which makes it possible for the S23 Ultra to be submerged up to 6.6 feet (or 1.5 meters) for 30 minutes. So if you plan to take the S23 Ultra to the pool, or even snorkeling or surfing, this case will keep it nice and dry, especially with the built-in screen and camera lens protectors. They’re made with tempered glass with 99.99% response sensitivity, it never scratches, and the camera lens protectors are crystal clear — giving you pristine photos and video.
Despite the bulky form factor, which is understandable considering that the case is meant to be waterproof, this Temdan offering allows for wireless charging compatibility. You also have military-grade drop protection on land, so your phone is safe from everyday wear and tear.
i-Blason Cosmo Series
The best colorful Galaxy S23 Ultra case
- Affordable
- Large variety of colors
- Built-in screen protector
- May be difficult to use with one hand
The i-Blason Cosmo Series is a collection of phone cases that are both stylish and protective. These Galaxy S23 Ultra cases are manufactured by i-Blason and can be purchased for various phone models, including Samsung. They are constructed from a soft and flexible TPU material that is designed to absorb shocks and protect your phone from scratches, dents, and drops. The cases come with a built-in screen protector to ensure that your screen remains safe from scratches.
The best part, though, is that all of that protection is also paired with fun designs. Whether you want deep blue shades that look like the ocean or a calming marble pink aesthetic, there's something for everyone.
VRS Design Damda Glide Pro Wallet Case
The best wallet Galaxy S23 Ultra case
- Rugged, shockproof protection
- Room for up to four cards in the backpack
- Affordable price
- Thick and bulky
- Blocks wireless charging
Traditional wallet cases are made from leather and have some slots to slip cards into. In other words, they're boring. The Damda Glide Pro case from VRS Design is anything but boring.
It's a big and rugged case that offers a lot of protection, and this makes it a good rugged case in its own right. But the best part of the case is near the bottom of the back of a case: a backpack that slides open to reveal a space for cards, cash, tickets, and more. It's a great everyday case that can replace your wallet and keep your precious phone safe — but it does take up a lot of space, so be prepared to have to make a lot of room in your pockets when you slip this beast on.
Spigen Cryo Armor Case
The best gaming Galaxy S23 Ultra case
- Super-cool design
- Relatively slim profile
- Tough and durable protection
- Heat ventilation for gaming sessions
- Pricey
Plan to do a lot of gaming on your Galaxy S23 Ultra? Then you want this super-cool Cryo Armor case from Spigen. It has a futuristic and distinctive pattern design that not only looks awesome, but also helps dissipate heat by providing ventilation, keeping your phone cool while you game. And like a lot of other Spigen cases, it has a pretty slim profile while offering tough protection at the same time.
Incipio Grip Case
The best grippy Galaxy S23 Ultra case
- Slim profile
- Grippy texture
- Tough protection
- Made from sustainable materials
- Only two colors
If you need extra grip on your new phone, check out Incipio’s Grip case for the Galaxy S23 Ultra. This case has a unique, textured pattern on the edges, which helps add more grip to the device overall, so you don’t drop it.
But if you do, “Impact Struts” inside absorb shock upon impact, keeping the S23 Ultra safe and sound. Raised edges around the screen and cameras protect those delicate glass parts from scratches and cracks. The Incipio Grip Case is also made from sustainable materials and comes in two neutral color options that are suitable for any setting and outfit.
Supcase Unicorn Beetle Pro Case
The best rugged Galaxy S23 Ultra case
- Affordable price
- Includes belt clip
- Several color choices
- Integrated kickstand
- Adds bulk to the S23 Ultra
The term "rugged" refers to cases that are built to withstand the most challenging tests, and this Su[case offering fits that description perfectly. It has been put through military-grade testing and is claimed to be shockproof, drop-proof, impact-resistant, and scratchproof. In other words, it offers a lot of protection, and a quick glance at it is enough to confirm that these are not just empty words.
This Galaxy S23 Ultra case has a dual-layer design that combines TPU and polycarbonate, providing excellent strength. It also features raised edges, ensuring that your phone does not come into contact with dirt or grit when placed on surfaces. It also has a kickstand on the back and a rotatable belt clip. Although this case is bulky, its more than reasonable price and strong protection make it an easy choice.

It has military-grade drop protection if you do actually drop it, so you have that peace of mind. What makes this one even more interesting is that Samsung also has a wide variety of accessories that are compatible with it, so you can deck it out however you choose, whether that's as a wallet case to carry a couple of cards on the back, a kickstand attachment for watching videos, or a ring to help ensure you can keep a solid grip on it.
Official Samsung Leather Case
The best leather Galaxy S23 Ultra case
- Genuine leather
- Slim and slender silhouette
- Looks elegant
- Extra grip
- Protects from everyday wear and tear
- Pricey
- May not be enough protection for some people
Those who like something minimal but elegant should consider the official Samsung Leather Case. This slim and slender case is made with genuine leather and is soft and supple to the touch.
It may not have the most rugged protection, but it is enough to keep your Galaxy S23 Ultra safe from everyday scratches and scuffs. As long as you aren’t too rough with it, then it should be fine. And since it’s leather, it will develop a rich patina over time, making it look unique and full of character.

A strong magnetic clasp holds the case closed to protect the expansive screen on your Galaxy S23 Ultra, while also providing room for up to three cards and a bit of cash inside.
It's also available in fun colors you don't usually find in folio cases, from a traditional chestnut brown to a bottle green that complements the green S23 Ultra finish.
Caseology Nano Pop
The best value Galaxy S23 Ultra case
- Military-grade drop protection
- Slim profile
- Very affordable
- Tight fit may cause problems with some screen protectors
The Caseology Nano Pop offers great bang for your buck, considering that you're getting certified military-grade drop protection in a slim, fun and stylish case.
Designed to fit your Galaxy S23 Ultra like a glove, the dual-layer TPU material has been tested to protect your phone for up to 26 drops from a height of 4 feet. There's also full protection around the camera section, with precise cutouts for each lens and a raised edge to protect the lenses from drops or simply being set down on a rough surface.
ESR Classic Kickstand Case
The best kickstand Galaxy S23 Ultra case
- Integrated kickstand doubles as camera guard
- Military-grade drop protection
- Unique frosted back
- Sides are a bit too smooth
While kickstand cases are a handy way to prop up your smartphone for watching videos, most of them add bulk by placing the kickstand right in the center of the case. However, ESR has taken a unique approach to this problem by turning the kickstand into a cover that protects the expansive camera array on your Galaxy S23 Ultra when it's folded up.
It's an ideal blend of form and function. It lets you prop your phone up in either landscape or portrait orientations at various angles for hands-free viewing of your favorite shows or participating in video calls. The case also provides military-grade drop protection, and the kickstand frame uses a durable zinc alloy and hinge. That means it's easy to open, won't damage your camera when closed, and you won't need to worry about wearing it out over time.
