Even though the Samsung Galaxy S23 Ultra is now officially an older flagship, it's still a device worth considering. With four years of OS updates and five years of security updates, the phone will still be supported through 2027. That's plenty of time to enjoy it if you still own one or you find a great deal. It's a rather large phone, however, with a 6.8-inch screen that you'll want to keep protected from damage.
The best way to do that, as with any phone, is via a protective case for your Galaxy S23 Ultra. While you want a case that looks good, the most important thing is that it's durable, offers good grip, and has features like raised lips and edges and shock-absorbent bumpers to assist with a bump, fall, scratch, or scuff. We have found that these are among the best Samsung Galaxy S23 Ultra cases.

Why you can trust Android Central Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
Best overall
A big case can be great for uncertain times, but some folks just want a bit of extra grip and scratch protection. That's where Thinborne cases come in. We love these ultra-thin Kevlar cases because they hug the S23 Ultra tightly and offer extra grip with minimal bulk. Choose from the ultra-thin version or the one that includes MagSafe built-in for a tiny bit of added thickness.
Best premium case
Carved cases are durable, comfortable, and totally unique. No, seriously, each and every case is completely unique and no two designs are the same! Each case is made with a durable, grippy rubber shell, complete with a back that's made from a mix of resin and real wood. They're hand made in Indiana and can be upgraded with MagSafe support and a wrist strap. You can even include a screen protector that's custom-cut to fit the case.
Best customizable case
It's lightweight, bold, and it's practical. Dbrand's Grip Case has non-slip sides with added texture for friction. On the material side of things, the S23 Ultra Grip Case comes in over 30 eye-catching designs, including solids, unusual patterns, and even its super-popular X-Ray design that shows you the insides of the phone.
Most stylish case
The stunning Samsung Galaxy S23 Ultra Case with Camera Cover comes in various colors, all of which are marbled and look incredible. These covers don't just look pretty though, they're sensible too. You get a sliding cover to protect the S23 Ultra's camera unit, and the case offers shockproofing against drops and falls.
Best MagSage case
Spigen has found a way to make Apple's MagSafe accessories compatible with the Samsung Galaxy S23 Ultra. The Ultra Hybrid OneTap Ring is a clear case that comes with a metal ring on the back. This means you can snap on any MagSafe accessory for Android, such as magnetic wallet add-ons and wireless chargers.
Best kickstand case
We loved this sheer case from TORRAS for the S22 Ultra and we love it on the S23 Ultra as well. The TORRAS MarsClimber for the Samsung Galaxy S23 Ultra has a hard TPU frame for better impact absorption, and a tiny pull-out kickstand at the back. Your Samsung phone can survive falls from as high as eight feet without batting an eyelash.
Best thin case
The Ringke Onyx S23 Ultra case has an interesting finish that almost looks like sandpaper. Combine that with the dark hues and you've got yourself an extremely classy phone cover. The anti-slip texture stays clean and prevents falls, and the reinforced corners absorb shocks and impacts. There are holes for a phone strap too, so you can easily carry your S23 Ultra worry-free.
Best basic case
Caseology's bright and lively Nano Pop series is a great match for the Samsung Galaxy S23 Ultra. This slim and trim cover fits the S23 Ultra like a glove, so it doesn't interfere with wireless charging. The insides are designed cleverly so the cover can withstand plenty of bumps and drops.
Best case bundle
Need a wallet case? The Ghostek EXEC cover is an unconventional take on one. Your S23 Ultra sits snugly inside, protected from all angles. When you're heading out, affix the handy wallet attachment magnetically to the back to stash cards and cash and leave your wallet at home. You get a case and accessory in one.
Best leather case
Looking for something more luxurious? Samsung has you covered with its genuine leather case for the Galaxy S23 Ultra. It has a slender profile so there's not much added bulk, and it provides all the necessary impact protection for the display and cameras. It also offer good grip, too.
Best fashion case
Incipio and Kate Spade's Defensive Hardshell Case consists of a semi-clear hard silicone case for mid-range protection in a fashionable pattern bedazzled with rhinestones. Style aside, this is one of the best slim cases we have tried for the S23 Ultra yet. It's surprisingly robust for a clear case and looks fabulous.
Best eco-friendly case
Whether you opt for the Impact, Ultra Impact, or Clear Case models, your Samsung Galaxy S23 Ultra will stay safe and secure inside your pick. CASETiFY has been a favorite with our team for a good reason. These eco-friendly bumper cases have rugged frames, come in an overwhelming number of designs to suit every personality, and they're made of recycled materials.
Best rugged case
We've arrived at a point in time when rugged covers no longer have to be ugly, chunky lumps of TPU. This shockproof Poetic Neon case for the S23 Ultra is a perfect example. It's a lean, cool-looking accessory with military-grade drop protection and bold colorways to choose from. The sides have textured bits at exactly the right places to add grip.
Best heavy-duty case
SUPCASE caters to the heavy-duty crowd. The Unicorn Beetle cover bolsters the S23 Ultra's defenses like no other, with raised edges all around. You get a rugged body made of tough materials that are meant to take a beating. There's a little stand that pops out of the back, which also acts as a grip since you can slip your fingers through it.
Best waterproof case
Of course, the Samsung Galaxy S23 Ultra already has an IP68 rating for water and dust resistance. But with this case, you get an additional layer of water protection. The hardy frame is black and it protects your phone from damage that occurs during bumps, shocks, or falls. The thick bezels are raised to prevent the screen and camera lenses from cracking and the buttons are tactile. You get a built-in screen protector too, and the case itself is IP68 rated.
Your S23 Ultra can conquer the world with the right case
Cases are the best form of protection for any device, be it a flagship Android phone or a cheap e-reader from Amazon. The S23 Ultra is now succeeded by the S24 Ultra (and soon to be the Galaxy S25 as well). However, if you already own last year's model, we suggest you shouldn't be in a big hurry to upgrade. There is no shortage of lovely covers and cases of shapes, colors, and sizes for the Samsung Galaxy S23 Ultra.
Slim cases look and feel great, but they don't usually help much with impact absorption. They do, however, weigh next to nothing and don't interfere with the S23 Ultra's wireless charging capability.
After trialing countless cases for the Samsung flagship, our favorite cases are the Incipio Kate Spade Hardshell Case, Thinborne Aramid Fiber Case for Galaxy S23 Ultra, Dbrand Grip Case, and Carved Traveler Case.
Folks who are looking for a super thin and lightweight case should pick either Thinborne's ultra-thin Aramid Fiber Case for Galaxy S23 Ultra or the Kate Spade Hardshell Case. The latter adds a lovely feminine look and a surprising level of toughness to your phone. You can also get the same thin case with a design from Coach from Incipio. Thinborne's case will add great scratch protection, extra grip, and optional Magsafe wireless charging magnets.
Carved and Dbrand go for a more unique, customizable angle. Both cases are wonderfully grippy and will survive a big fall without feeling bulky or heavy. Dbrand features the company's trademark sarcasm and consistent patterns, while Carved cases are handmade and completely unique.
If those are too much, the Ringke Onyx features a great, non-slip texture and it has holes for strap attachments. You can also opt for the Caseology Nano Pop for something brighter and more protective. Carved and Dbrand also make gorgeous, unique cases with grippy rubber sides that'll let you show off your style. If you want something simple and sophisticated, you can't go wrong with the leather cases from Samsung.
Heavy-duty cases like the Poetic Neon go a long way to help with shocks and scrapes. This sleek cover comes in plenty of colorful hues and it has multiple layers to add military-grade drop protection. SUPCASE brings you all of these things in the form of the Unicorn Beetle case, but it sacrifices sleekness for the extra kickstand on the back. You can't go wrong with either pick for your S23 Ultra.
After snagging the right case, don't forget to grab a robust screen protector for your S23 Ultra. The last thing that a beautiful AMOLED panel needs is a big ugly crack running through it!
