Whether you’re into bold florals, soft pastels, fierce prints, or full-on beach-day energy, buy a case with a design that fits your vibe. You never have to choose between being cute and being practical. Here are our top 10 best cases for the Samsung Galaxy S25 Ultra. 

1. Wild at Heart | Tiger Case

If you live for main-character energy, you’ll grab the Wild at Heart | Tiger Case the second you see it. You get fierce tigers, romantic florals, and cosmic symbols, all on a sleek black backdrop that makes your S25 Ultra look like it belongs in a fantasy action movie.

2. Queen of Diamonds | Pink Watercolor Case

You love a little softness, but you also refuse to blend in, and the Queen of Diamonds | Pink Watercolor Case totally gets you.

With this case, you’ll look both sweet and striking every time you pick up your phone.

3. Poppy Meadows | Pastel Floral Case

You bring spring with you everywhere, and the Poppy Meadows | Pastel Floral Case matches your vibe perfectly.

4. Chateau Pups | French Dog Case

If you love dogs, Paris, or both (obviously both), the Chateau Pups | French Dog Case adds instant Parisian charm to your S25 Ultra.

Frequently Asked Questions

Do S24 Ultra Cases Fit the S25 Ultra?

No. While the two phones might look identical in size, they’re just different enough that their cases aren’t interchangeable. The S25 Ultra is a little narrower, shorter, and thinner than the S24 Ultra, and it also has slightly rounded corners instead of the sharper edges on the S24 version.

Does the Samsung Galaxy S25 Ultra Need a Case?

Absolutely. Your smartphone isn’t cheap, so you need to protect it. Even though the Samsung Galaxy S25 Ultra has premium materials and durability upgrades, daily drops and scuffs still happen. A phone case prevents drops from bricking your phone and protects your investment. Just make sure you buy a case you love and that it fits the S25 Ultra’s specs.
