The gluteus maximus muscle is the largest and strongest of the gluteal muscles. It is the most superficial layer of the dorsal gluteal musculature and therefore forms the surface anatomy of the gluteal region.

The gluteus maximus has several origins on the pelvic bones as well as the sacrotuberous ligament and inserts at the gluteal tuberosity of the femur. The innervation is supplied by the inferior gluteal nerve.

The gluteus maximus muscle is the strongest extensor and outward rotator of the hip and is also involved in adduction and abduction as well as stabilization of the hip joint. With its insertion at the iliotibial tract it also contributes in relieving weight pressure of the femur via the tension band principle.
