The greater trochanter of the femur, historically known as trochanter major, is a large, irregular, quadrilateral eminence and a part of the skeletal system.

It is directed lateral and medially and slightly posterior. In the adult it is about 2-4 cm lower than the femoral head. Because the pelvic outlet in the female is larger than in the male, there is a greater distance between the greater trochanters in the female.
