Maryland Million Lassie 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.
The race is part of Maryland Million Day, a 12-race program held in mid October that was the creation of renowned television sports journalist Jim McKay.
In addition to the prize money, the winning owner receives a Maryland Million Waterford Crystal bowl.
In its 30th running in 2015, the race was restricted to those horses who were sired by a stallion who stands in the state of Maryland.
Both the entrant horse and their stallion had to be nominated to the Maryland Million program.
