Darrell Wayne Lukas (born September 2, 1935, in Antigo, Wisconsin) is an American horse trainer and a U.S.

He graduated from the University of Wisconsin–Madison with a master's degree in education then taught at La Crosse, WI Logan High School where he was a head basketball coach.

In 2024, the 88-year-old Lukas broke Fitzsimmons' record as the oldest trainer to win a Triple Crown race when Seize the Grey won the Preakness Stakes.

In 1999, the same year his horse Charismatic came within 2 lengths of the Triple Crown, he was inducted into the National Museum of Racing and Hall of Fame.

In a shedrow accident at Santa Anita Park, the colt broke loose and when Jeff Lukas tried to stop him, the horse slammed into him, throwing him into the air and when Jeff landed on the concrete, he suffered a skull fracture which left him in a coma for several weeks.

By spring of 1994, he had recovered enough to attempt a return to horse racing but after a series of less-demanding jobs ending in 2003, it was clear he could not work safely around racehorses.

He ultimately moved to Atoka, Oklahoma in 2007 to work for David Burrage, who had been the accountant and general manager for Lukas Racing Stables.
