The adductor longus, a muscle of the medial compartment of the thigh, is triangular in shape and forms in the floor of the femoral triangle and adductor canal.

The muscle has its origin on the anterior surface of the pubic body below the pubic crest i.e. the superior pubic ramus (just lateral to the pubic tubercle). It's insertion is then found on the middle third of the medial lip of the linea aspera. This insertion point is lateral to the adductor magnus and brevis insertions, but medial to the insertion of vastus medialis (one of the four components of quadriceps femoris).

The adductor longus recieves its innervation by the anterior division of the obturator nerve. All three adductors (except the hamstring part of the adductor magnus) and gracilis are supplied by the obturator nerve (anterior divisions of the ventral rami of L2L4).

The main action of the adductor group of muscles is to adduct the thigh at the hip joint. The adductor longus muscle also participates in external/lateral rotation and flexion of the thigh.
