Mejiro McQueen (Japanese : メジロマックイーン, April 3, 1987 - April 3, 2006) was a Japanese Thoroughbred racehorse and sire. He was a late-maturing horse who did not emerge as a top-class performer until the autumn of his three-year-old season when he won the Kikuka Sho. Over the next three years he proved himself one of the best stayers in Japan with wins in the Tenno Sho (twice), Takarazuka Kinen, Osaka Hai, Kyōto Daishōten (twice) and Hanshin Daishoten (twice). He won the JRA Award for Best Older Male Horse in 1991 and was inducted into the Japan Racing Association Hall of Fame shortly after his retirement from racing.
