Question: has a female horse ever won the triple crown

Answer: No, Each Triple Crown race is open to both colts and fillies. Although fillies have won each of the individual Triple Crown races, none has won the Triple Crown itself. Despite attempts to develop a ``Filly Triple Crown'' or a ``Triple Tiara'' for fillies only, no set series of three races has consistently remained in the public eye, and at least four different configurations of races have been used. Two fillies won the series of the Kentucky Oaks, the Pimlico Oaks (now the Black-Eyed Susan Stakes), and the Coaching Club American Oaks, in 1949 and 1952, but the racing press did not designate either accomplishment as a ``triple crown''. In 1961, the New York Racing Association created a filly triple crown of in-state races only, but the races changed over the years. Eight fillies won the NYRA Triple Tiara between 1968 and 1993.
