New Cozy Mystery Movies to Watch This Summer (2026 Guide)
Summer is the perfect season for slowing down, grabbing your favorite snack, and settling in with a mystery that keeps you guessing without keeping you up all night. While 2026 hasn't delivered a huge number of cozy mystery films, the releases we have received are packed with charming detectives, quirky suspects, picturesque settings, and plenty of satisfying sleuthing.
Whether you're planning a family movie night, a girls' night in, or simply looking for your next cozy watch, these four new releases deserve a spot on your summer watchlist.
The Sheep Detectives
If there were an award for the most delightfully original cozy mystery of the year, The Sheep Detectives would be a strong contender.
Based on Leonie Swann's beloved novel Three Bags Full, this mystery comedy follows a flock of sheep determined to solve the murder of their shepherd before the humans can.
