The tensor fasciae latae is a muscle of the thigh. It has origins in the anterior superior iliac spine as well as the anterior aspect of the iliac crest, and inserts into the iliotibial tract. It plays a role in thigh flexion and medial rotation.

The tensor fasciae latae (tensor fasciae femoris) arises from the anterior part of the outer lip of the iliac crest; from the outer surface of the anterior superior iliac spine, and part of the outer border of the notch below it, between the gluteus medius and sartorius; and from the deep surface of the fascia lata. It is inserted between the two layers of the iliotibial band of the fascia lata about the junction of the middle and upper thirds of the thigh.
