The psoas minor is an inconstant muscle, absent in roughly 40 percent of people, lying on the front of the psoas major. It arises from the bodies of T12 and L1 and their intervening disc and ends in a long, flat tendon. The tendon inserts on the pectineal line and iliopubic eminence and blends with the iliac fascia.

Because it is often absent, the psoas minor tendon is mainly of interest as an anatomical variant seen on imaging or at surgery. When present it lies anterior to the psoas major and can be mistaken for part of the iliopsoas tendon. A tight psoas minor tendon has been described as a rare cause of groin pain and snapping.
Overload of the tendon during resisted trunk or hip flexion can cause deep anterior pelvic or groin pain, usually managed conservatively.
