Top sirloin is a cut of meat from the primal loin, subprimal sirloin, of a beef carcass. Top sirloin steaks differ from sirloin steaks in that the bone and the tenderloin and bottom round muscles have been removed; the remaining major muscles are the gluteus medius and biceps femoris (top sirloin cap steak). Some American butchers call a thick top sirloin steak a chateaubriand, although the French reserve that term for a more premium cut from the tenderloin.
