Maid At Arms (foaled 1922 in Kentucky) was an American Champion Thoroughbred racehorse. Her sire was Man o' War, a son of three-time Leading sire in North America Fair Play. Her dam was Trasher, a daughter of Trap Rock. Maid At Arms is probably best remembered for her victory in the seventh running of the Black-Eyed Susan Stakes on May 4, 1925.
