"Hollywood" is a song recorded by American recording artist Jay-Z for his ninth studio album, Kingdom Come (2006). It features Jay-Z's now-wife, American recording artist Beyoncé Knowles, and was released as a single in the US on January 23, 2007. It was composed by Jay-Z, Shaffer 'Ne-Yo' Smith, and Reggie "Syience" Perry. "Hollywood" is a disco-influenced R&B song with lyrics that detail the tiredness music stars, working in the American cinema industry, sometimes feel. The song was well received by music critics who praised its musical arrangement as well as the guest vocals by Knowles.

"Hollywood" charted on US Billboard component charts, reaching a peak of number 56 on the Hot R&B/Hip-Hop Songs chart in early March 2007. It also gained attention in Australia where it charted inside the top 100 positions of the ARIA Singles Chart. Knowles later recorded a solo version of the song, which was re-titled "Welcome to Hollywood", and included it on the deluxe edition of her second studio album, B'Day (2006). A video interlude was recorded for The Beyoncé Experience tour where clips of Knowles were shown and music videos from her B'Day Anthology were comprised together, while the song was played on the tour.
