Maryland Million Oaks is an American Thoroughbred horse race held annually in October since 1986 primarily at Laurel Park Racecourse in Laurel, Maryland or at Pimlico Race Course in Baltimore. To be eligible for the Maryland Million Oaks, a horse must be sired by a stallion who stands in Maryland. Due to that restriction the race is classified as a non-graded or "listed" stakes race and is not eligible for grading by the American Graded Stakes Committee.
