Harlequin (Lady Gaga album)

Harlequin is a soundtrack album by American singer-songwriter Lady Gaga, released on September 27, 2024, by Interscope Records. It was produced by Gaga, alongside BloodPop, David Campbell, Jason Ruder, and Benjamin Rice. The record is musically inspired by and includes alternate takes of songs from the soundtrack for the musical thriller film Joker: Folie à Deux (2024), in which Gaga portrays the DC Comics character Harley Quinn. Gaga stated that Harlequin serves as a "companion album" to the film, while some publications have referred to it as a soundtrack album, alongside the film's official soundtrack released a week later. Thematically, however, critics described Harlequin as a concept album about Harley Quinn, depicting the supervillain from Gaga's perspective.

The album consists of covers of American jazz standards, as well as two original compositions by Gaga, expanding her venture into jazz music following her collaborative albums with American jazz singer Tony Bennett: Cheek to Cheek (2014) and Love for Sale (2021). In promotion of Harlequin, she released a video shot in the Louvre, featuring her rendition of "The Joker", and gave a televised performance of original song "Happy Mistake". Days after the album's release, she performed the entire record during an intimate show at The Belasco in Los Angeles, which was later commemorated in the concert film Lady Gaga in Harlequin Live: One Night Only, released in December 2025.

Upon release, Harlequin received mostly positive reviews from music critics, who praised Gaga's theatrical presence, vocal performance, and her syncretic interpretation of Harley Quinn through the Great American Songbook, though some reviews noted similarities with her previous jazz-oriented projects alongside Bennett. It was later nominated for Best Traditional Pop Vocal Album at the 68th Annual Grammy Awards. Commercially, the album reached the top 10 in Austria, France, Germany, Scotland, Spain and Switzerland as well as the top 20 in Belgium Wallonia, Italy, Sweden, the United Kingdom and the United States. Additionally, it topped the US Jazz Albums chart, marking Gaga's third number-one album there.
