The muscles that act on the posterior thigh are primarily involved in extension, abduction and external rotation of the thigh in the hip joint.

These muscles originate at different parts of the pelvis to insert on the structures of the posterior thigh.

One prominent muscle group that acts on the posterior thigh are the gluteal muscles on the buttocks. The gluteus maximus muscle is the strongest extensor of the hip joint and the gluteus medius muscle the strongest hip abductor.
