The Monterey Jazz Festival is an annual music festival that takes place in Monterey, California, United States. It debuted on October 3, 1958, championed by Dave Brubeck and co-founded by jazz and popular music critic Ralph J. Gleason and jazz disc jockey Jimmy Lyons.

Monterey is a city in Monterey County on the southern edge of Monterey Bay on the U.S. state of California's Central Coast. Founded on June 3, 1770, it functioned as the capital of Alta California under both Spain (1804–1821) and Mexico (1822–1846). During this period, Monterey hosted California's first theater, public building, public library, publicly funded school, printing press, and newspaper. It was originally the only port of entry for all taxable goods in California. In 1846, during the Mexican–American War of 1846–1848, the United States Flag was raised over the Customs House. After Mexico ceded California to the U.S. at the end of the war, Monterey hosted California's first constitutional convention in 1849.
