Samsung's Galaxy S21 is a few years old now, but it still holds up quite well against all the modern flagships, including the Galaxy S23 series. It arguably looks better than even the Galaxy S23 with its contour-cut design, and it's easily one of the best-looking phones in 2023. It's still qualified to receive Android OS and security updates directly from Samsung, so there's no reason to upgrade unless you really want to upgrade to a new phone.

Whether you picked up a new or renewed unit today or have had one since launch, you can always consider buying a new case for the Galaxy S21 to switch things up and give it a fresh look. A good quality case will not only change the look and feel of the device, but it'll also protect it from accidental drops and scuffs. There are plenty of cases available for the Galaxy S21 on the market, so I've highlighted the best ones to make it easier for you to pick the right one. Let's dive in!

This article only covers cases for the regular Galaxy S21 model. Check out our Galaxy S21 Plus cases and Galaxy S21 Ultra case round-ups in case you're buying the other phones in the lineup.
