Jim McKay Maryland Million Day ranks as the highest single day in attendance, on-track wagering and simulcast handle for Laurel Park Racecourse in Laurel, Maryland annually.

Jim McKay first conceived the idea of a day of races for Maryland-sired runners after attending the first Breeders' Cup in 1984. In September 1985, a nationally attended press conference at Pimlico outlined the details for a 9-race, $1 million program and introduced the 18-member Maryland Million committee. Richard W. Wilcke was named executive director of the Maryland Million. In December 1985, a total of 175 stallions were nominated to the Maryland Million by the first deadline, thus making their foals eligible for the program. Windfields Farm topped all nominators with 16 stallions, led by Northern Dancer, The Minstrel and the deceased Tentam. Nearly 900 horses of racing age were nominated by the May 15, 1986 deadline, at least 88 of them stakes winners or stakes placed. Another 700 yearlings were also nominated.
20,103 turn out at Laurel Park for the first Maryland Million Day on October 20, 1986. Northern Dancer sired two winners - Classic winner Herat and Turf Winner Glow. The first winner of a Maryland Million race was Sam-Son Farm's Canadian-bred Smart Halo. Sired by Windfields Farm's stallion Smarten, she captured the Lassie for 2-year-old fillies.
Governor William Donald Schaefer proclaimed the week leading up to the Maryland Million "Thoroughbred Week in Maryland", September 11-18, 1988.
On April 13, 2009, the Maryland legislature passed a joint resolution to officially rename the event "Jim McKay Maryland Million Day".
The world-famous Waterford Crystal factory in Ireland produced the unique trophies for Maryland Million Day. The permanent Maryland Million Trophy - a special 14" bowl that includes logos of all the first-year sponsors - is the largest single piece of hand-blown glass made in the company's history.
