Fiesta de Las Flores began as La Fiesta de Los Angeles, an annual multi-day event celebrating Los Angeles and Southern California's cultural heritage. The first celebration was held in April 1894. Canceled during the Spanish-American War, it was revived in 1901 under the new name La Fiesta de las Flores, and it continued through the 1940s.

The floral elements used in the floats of in the parade are the same as those in the Tournament of Roses Parade, which began four years earlier and still continues to this day.
