I love murder mystery movies, so I rounded up 50 of the most thrilling, clever, and fun "whodunit" films that'll actually make your jaw drop. Some of these movies will keep you guessing the entire time, while others are a bit more straightforward, but all of them are genuinely great. From underrated gems to Old Hollywood classics to 2026 releases, here are the must-see murder mystery movies that I promise you'll love. Enjoy!

Obviously I couldn't feature ~every~ movie on this list, so if one of your favorites is missing, then please feel free to share it in the comments!
