The Galaxy S21 Ultra is one of the biggest and most powerful Galaxies ever, as well as being the first to work with the S Pen, traditionally reserved for the Note line. The camera module on the Ultra is just as big as it was on the S20 Ultra, but the design's been improved so that it looks more cohesive and meshes with the phone's metal frame, but that design also means that you're more prone to damage the cameras with a side-impact, so a case is more important than ever. The best cases for the Galaxy S21 Ultra are right here, whether you're after a clear case to show off the Ultra's design or a durable tank to keep it safe and secure.

The S21 Ultra is made for productivity, so it should come as no surprise that one of my favorite S21 Ultra cases features a nice, sturdy kickstand that works in portrait mode so you can prop it up next to your computer, or while doomscrolling at the dinner table. The launch colors are nice, too, with the Purple and Red version looking especially fetching.
ESR's clear cases are slim as can be, allowing you to see every millimeter of Samsung's design while guarding it from scratches and adding some much-needed grip to this extra-large phone. It adds the slimmest of margins while giving you peace of mind. ESR also has bundles so you can snag some screen protectors alongside the clear case.
While most hybrid cases have a softer inner sleeve and a hard outer shell, this Pulen multi-layer case instead has a hard frame that snaps around your S21 Ultra and then slips into a more flexible and impact-resistant case. The color options here are wonderful, and you also get a screen protec tor in the box.
Folio cases let us guard that big, bright, beautiful screen while also adding extra functionality with wallet flaps to hold cards and cash. This wallet folio has small magnetic clasps on the side, keeping it closed but not getting in the way when open.
While Sucnakp might be better known for its more heavy-duty cases, I'm a fan of the classic TPU case with carbon fiber accents. Available in Navy Blue or Black, this case will add grip to your S21 Ultra without bulking it up. Despite the low profile, there's still air cushioning in the corners to help absorb the impact of a small drop.
The Camera module on the S21 Ultra is more robust that its little sisters, but that, unfortunately, means that it's more exposed. Protect your cameras and your investment with this hybrid case, which features a sliding camera cover to guard your lenses from scratches.
This clear case features a frosted glass across the back, letting the Samsung branding show through just enough while concealing scratches and scuffs you may have picked up along the way. The matte blue bumper around the edges also gives you a pop of color.
Hey, if you're going to get a big, heavy-duty case for this big, heavy phone, might as well make use of the space. You can keep a couple of credit cards or some cash concealed inside while also guarding your S21 Ultra from drops and dings.
If you don't want to bulk up your Galaxy S21 Ultra any more than absolutely necessary, Anccer's thin, hard-shell will give you some added grip and scratch protection without making this super-sized phone any harder to fit in your pocket.
The color options for the S21 Ultra are both monochromatic, so if you want some color in your Ultra, you'll need a bright and beautiful case. Weycolor's silicone case is slim, grippy, and gives you some nice, natural shades of yellow, green, and blue to choose from.
What makes the best cases for the Galaxy 21 Ultra?
There's usually a half-dozen factors to consider and juggle when choosing a case, but for a phone as physically large and heavy as the Galaxy S21 Ultra, durability and grip have to be top of the list. Heavy-duty cases for the Galaxy S21 Ultra are bound to draw a lot of attention for higher drop-testing and extra functionality such as the kickstand on the ArmadilloTek Vanguard Series, which is durable and dependable while injecting some color. If you want protection without getting a bulky case, there are some slightly slimmer hybrid cases like the Pulen Three Layer, too.
On the thinner side of the spectrum, the Anccer Ultra Thin and the ESR Clear Case both offer increased grip and scratch protection while keeping your Galaxy S21 Ultra as svelte as possible. I'm partial to the candy color of the Anccer — especially since the Ultra doesn't get Phantom Violet or Phantom Pink like the smaller models — but if you want to show off the shiny silver of your Phantom Silver, the ESR Clear is an excellent option, too.
While you're buying your new phone a case, though, don't neglect the screen, because if your front glass shatters, all you're left with is an expensive paperweight. The Best Galaxy S21 Ultra Screen Protectors will ensure that your touchscreen remains pristine and perfect for years to come.
