The Hollywood Derby is a Grade I American Thoroughbred horse race held annually in late November/early December. Now held at Del Mar racetrack in San Diego, California, until 2014 it was held at Hollywood Park Racetrack in Inglewood, California. The race is open to horses aged three and contested at a mile and an eighth on turf. It currently offers a purse of $300,000. Inaugurated in 1938, the race has been a Grade I event since 1973 when grading was first introduced. There was no race from 1942 through 1944 as a result of World War II and it was not run in 2005 as a safety precaution after new grass had been planted on the turf course. It was contested in two divisions from 1981 through 1987. Known as the Westerner Stakes from 1948–1958, the race was held at Santa Anita Park in 1949 after a fire destroyed the Hollywood Park grandstand and clubhouse. When Hollywood Park closed in December 2013, the race was transferred to Del Mar. Due to the layout of the turf course at Del Mar, the race was shortened to miles. Only five fillies have ever won the race: Busher (1945), Honeymoon (1946), A Gleam (1952), De La Rose (1981) and Royal Heroine (1983). In 2014, California Chrome accomplished a rare feat when, having won the Santa Anita Derby, Kentucky Derby and Preakness Stakes on dirt earlier in the year, he won the Hollywood Derby in his first appearance on the turf.
