Patrick Alan "Pat" Day is an American jockey. He is a four-time winner of the Eclipse Award for Outstanding Jockey and was inducted into the National Museum of Racing and Hall of Fame in 1991. Day also received the George Woolf Memorial Jockey Award in 1985, given annually to a North American jockey who demonstrates the highest standards of professional and personal conduct. In 1995, he was voted the Mike Venezia Memorial Award for "extraordinary sportsmanship and citizenship".
Day has ridden winners of U.S. Triple Crown races nine times. Day was quoted in a recent interview on the TVG Network's "Legends" program that Easy Goer was the best horse he ever rode in his career. In 1999 he rode Menifee, who placed directly behind Charismatic in both the Kentucky Derby and the Preakness Stakes. Prior to the Belmont Stakes, where Menifee failed to place in the top three and Charismatic broke down in the final furlong, their rivalry was compared to that of Affirmed and Alydar in 1978.
In 1991, Pat Day won the Canadian Triple Crown and the Breeders' Cup Distaff aboard the future Hall of Fame filly Dance Smartly. He is the only jockey to have ridden at least one mount in each of the first 20 Breeders' Cups, and ranks second all-time in Breeders' Cup winners, with 12.
