Hollywood is a district in Los Angeles, California, U.S.A., situated west-northwest of Downtown. Due to its fame and cultural identity as the historical center of movie studios and stars, the word "Hollywood" is often used as a metonym for the American film and television industry. Today much of the movie industry has dispersed into surrounding areas such as Burbank and the Westside, but significant ancillary industries (such as editing, effects, props, post-production, and lighting companies) remain in Hollywood.

Many historic Hollywood theaters are used as venues to premiere major theatrical releases, and host the Academy Awards. It is a popular destination for nightlife and tourism, and home to the Walk of Fame.

There is currently no official boundary of Hollywood (Los Angeles does not have official districts), but the 2002 secession movement and the current Neighborhood Council boundaries can serve as guides. There is a sign at the northeast corner of Fairfax Avenue and Melrose Avenue indicating that one is entering Hollywood. Generally, Hollywood's southern border follows Melrose Avenue from Vermont Avenue west to Fairfax Avenue. From there, the boundary continues north on Fairfax, wrapping east around the separate City of West Hollywood along Willoughby Avenue then wrapping around on La Brea and heads west along Fountain Avenue before turning north again on Laurel Canyon Boulevard into the Hollywood Hills. The eastern boundary follows Vermont Avenue north from Melrose past Hollywood Boulevard to Franklin Avenue. From there, the border travels west along Franklin to Western Avenue, and then north on Western into Griffith Park. Most of the hills between Laurel Canyon and Griffith Park are part of Hollywood. The commercial, cultural, and transportation center of Hollywood is the area where La Brea Avenue, Highland Avenue, Cahuenga Boulevard, and Vine Street intersect Hollywood Boulevard and Sunset Boulevard. The population of the district is estimated to be about 300,000.

As a portion of the City of Los Angeles, Hollywood does not have its own municipal government, but does have an appointed official that serves as "honorary mayor" for ceremonial purposes only. Currently, the "mayor" is Johnny Grant.
