Looking for the best of the best? Samsung's Galaxy S23 Ultra is in the running to be considered the baddest of the bunch, running right up against the iPhone 14 Pro as the best smartphone overall, and being unquestionably the best Android smartphone available today.
It's not alone in being excellent — the rest of the Samsung Galaxy S23 series is similarly amazing, but the big and powerful Galaxy S23 Ultra is the most expensive of the three. It starts at $1,200 retail, but it's a solid investment considering that it could easily be the only smartphone you'll need for years to come — it delivers performance like nothing we've ever seen before, and you're guaranteed updates through Android 17.
But all that only applies if it can physically go the distance and isn't wrecked by a tumble onto concrete or other solid ground. The best Galaxy S23 Ultra cases can help stop that from happening, and we've rounded up the best picks below to offer something for everyone.
Ringke Fusion-X Case
Best lanyard case for the Galaxy S23 Ultra
- 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
Best kevlar case for the Galaxy S23 Ultra
- Excellent all-around protection
- Cool sci-fi design
- 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
Best adventure case for the Galaxy S23 Ultra
- 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
Best belt clip case for the Galaxy S23 Ultra
- Great OtterBox protection
- Versatile accessories
- Adds bulk
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
Best sparkly case for the Galaxy S23 Ultra
- 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.

Best slim case for Galaxy S23 Ultra
- Slim and minimal design
- Anti-slip texture
- Sliding camera lens protector
- Flexible yet robust protection
- Available in a single, black color

The sliding camera cover also keeps the triple-lens camera system safe from small particles and debris when not in use.
Temdan Full Body Waterproof Case
Best waterproof case for Galaxy S23 Ultra
- 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.

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.
AICase Tough Case
Best colorful case for Galaxy S23 Ultra
- Affordable OtterBox Defender dupe
- Large variety of colors
- Rugged and tough multi-layer protection
- Very large

Want OtterBox Defender protection but for a fraction of the cost? This case from AICase is a good alternative. It’s made with synthetic rubber, polycarbonate, and TPU to form a multi-layer case that will withstand anything life throws at it. AICase’s Tough Case also has higher raised edges that will keep the screen and cameras safe from small particles, and the port covers prevent any dust and debris from getting inside. And with a large variety of colors, you can find one that suits your preferences perfectly — or just goes best with your chosen S23 Ultra color.
Marphe Wallet Case
Best wallet case for Galaxy S23 Ultra
- Rugged, shockproof protection
- Hidden compartment holds up to four cards
- Precise cutouts for all ports and S-Pen
- Responsive and tactile buttons
- Affordable price and multiple colors
- No wireless charging
Love the convenience of having your phone and wallet in one? Then this affordable case is worth a look.

On the back, a hidden flip-slot compartment can hold up to four cards, such as your debit and credit cards, folded receipts, and ID. The precise cutouts make accessing the ports easy, and the buttons remain tactile and responsive through the covers.
The only negative is that there is no wireless charging compatibility due to the fact that the card compartment interferes with it. But this wallet case comes in three colors and costs less than a Jackson, so it's a fine compromise considering everything else the case has to offer.
Spigen Cryo Armor Case
Best gaming case for Galaxy S23 Ultra
- Super-cool design

- Tough and durable protection
- Heat ventilation for gaming sessions
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
Best grippy case for Galaxy S23 Ultra
- 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 case also has a toughened glass screen protector to keep the front of the screen protected, and there is also a tempered glass camera lens protector as well. An integrated kickstand can be found on the back that also doubles as a phone grip. However, because of the built-in kickstand, wireless charging will not work — the case must be removed if you want to wirelessly charge the Galaxy S23 Ultra, or use the Wireless PowerShare feature.
Still, if you need rugged protection, this case is a solid choice, and it won’t break the bank. It also comes in a variety of fun colors.

ESR Classic Kickstand Case
Best kickstand case for Galaxy S23 Ultra
- 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.
