In human anatomy, a hamstring (/ˈhæmstrɪŋ/) is any one of the three posterior thigh muscles in between the hip and the knee (from medial to lateral: semimembranosus , semitendinosus and biceps femoris ). The hamstrings are susceptible to injury. In quadrupeds, the hamstring is the single large tendon found behind the knee or comparable area.
