The gluteus minimus (also gluteus minimus muscle, latin: musculus gluteus minimus) is the smallest of the three gluteal muscles lying below the gluteus medius.
The gluteus minimus originates between the anterior and inferior gluteal lines of the ileum. The gluteus minimus inserts at the greater trochanter of the femur.
The main functions of the gluteus maximus muscle are to abduct and internally rotate the hip. The contractions of the anterior fibers of the gluteus minimus result into flexion and internal rotation, but the contractions of the posterior fibers result into external rotation of the hip.
