The gluteus maximus is the largest single muscle in the human body by mass.  There are three gluteus muscles (maximus, medius, and minimus) that help connect the femur to the pelvic bone.  The gluteus maximus gives shape to the buttocks.  The reason that it is the largest muscle in the body is because it is mostly responsible for keeping the pelvic portion of the body in an erect position.  It must be strong to keep the upper body supported through the pelvis on the femur bone (thigh).  Since it is constantly being used to keep balance, the muscle gets used often and maintains its large mass.
