Sunset Boulevard is a musical with book and lyrics by Don Black and Christopher Hampton and music by Andrew Lloyd Webber. Based on the 1950 film of the same title, the plot revolves around Norma Desmond, a faded star of the silent screen era, living in the past in her decaying mansion on the fabled Los Angeles street. When young screenwriter Joe Gillis accidentally crosses her path, she sees in him an opportunity to make her comeback to the big screen. Romance and tragedy follow.

Opening first in London in 1993, the musical has had several long runs internationally and also enjoyed extensive tours, although the show, which has been the subject of several legal battles, lost money because of its extraordinary running costs.

From approximately 1952 to 1956, Gloria Swanson worked with actor Richard Stapley (aka Richard Wyler) and cabaret singer/pianist Dickson Hughes on a musical adaptation originally entitled Starring Norma Desmond, then Boulevard! It ended on a happier note than the film, with Norma allowing Joe to leave and pursue a happy ending with Betty. Paramount originally had given Swanson verbal permission to proceed with the musical, but there had been no formal legal arrangement. On February 20, 1957, Paramount executive Russell Holman wrote Swanson a letter in which he asked her to cease work on the project because "it would be damaging for the property to be offered to the entertainment public in another form as a stage musical." In 1994, Hughes incorporated material from the production into Swanson on Sunset, based on his and Stapley's experiences in writing Boulevard!. A recording of the entire score, which had been housed in the Gloria Swanson archives at the University of Texas, was released on CD in 2008.

Sunset Boulevard is a street in the western part of Los Angeles County, California, that stretches from Figueroa Street in downtown Los Angeles to the Pacific Coast Highway at the Pacific Ocean in the Pacific Palisades. The street is an icon of Hollywood celebrity culture and the phrase "Sunset Boulevard" is an enduring shorthand for the glamor associated with Hollywood.

Approximately 24 miles (39 km) in length, the famous boulevard roughly mimics the arc of the mountains that form the northern boundary of the Los Angeles Basin. From downtown Los Angeles, it heads northwest, to Hollywood, through which it travels due west for several miles before it bends southwest, on course to the Pacific. It passes through or near Echo Park, Silver Lake, Los Feliz, the aforementioned Hollywood, West Hollywood, Beverly Hills, Holmby Hills, Bel-Air, Brentwood, and Pacific Palisades. Other than West Hollywood and Beverly Hills, which are independent incorporated cities, the places named above are all districts and neighborhoods in the City of Los Angeles. In the Bel-Air district of Los Angeles, Sunset Boulevard runs along the northern boundary of the UCLA Westwood campus, and it also serves as the postal divider between north and south west of Beverly Hills.
