The Cumberland slider (Trachemys scripta troostii), also called commonly the Cumberland turtle and Troost's turtle, is a subspecies of semiaquatic turtle, or terrapin, in the family Emydidae. The subspecies is indigenous to the Southeastern United States. The carapace of T. s. troostii is olive brown with yellow markings. It has two rounded projections on the posterior edge of the shell, and is slightly keeled. The adult carapace is wrinkled and oval shaped. The plastron is hingeless and slightly smaller than the carapace. Each of the bottom sides of the marginals has a spot. The skin is brown with an olive to greenish tint with yellow striping. There is a distinct bar behind the eyes that can vary from yellow to red and be either thin or wide. The plastron of the turtle has dark spots, as well as the ridge of the carapace. Also, the plastron has bars or stripes of yellow. The turtle's legs in front have larger yellow stripes than most slider species. There is a yellow and orange stripe directly behind each eye. The stripe is never entirely one color, it starts out yellow and then fades into a dark orange-to-red color closer to the back of the neck.
