Mairzy Doates (foaled 1 April, 1976 in Kentucky) was an American Thoroughbred racehorse and four time graded stakes winner. She was owned by New York City art dealer Arno D. Schefler who bought her as a weanling from breeder Preston W. Madden. Schefler named her for the novelty song "Mairzy Doats" made popular in a 1943 recording by bandleader Al Trace.

Trained by future U.S. Racing Hall of Fame inductee, Horatio Luro, in 1981, Mairzy Doates competed successfully at racetracks in Florida, California and New York. By July of the year, she was considered a leading contender for turf-racing fillies in North America. In November, she went to Tokyo, Japan where she beat an international field to win the inaugural Japan Cup.
