The Los Alamitos Derby (formerly the Swaps Stakes) is a race for Thoroughbred horses run annually at Los Alamitos Race Course in Los Alamitos, California. The race is open to three-year-old horses and is contested at one and one-eighth miles on the dirt. A Listed event, it currently carries a purse of $150,000. Before 2014, the race was called the Swaps Stakes and was run at Hollywood Park Racetrack before its closure in 2013. At that point, it moved to Los Alamitos.
