Bummed is the second studio album by English rock band Happy Mondays, released on 21 November 1988 on Factory Records. During 1987 and early 1988, the band discovered house music and the rave drug ecstasy. Factory producer Martin Hannett was subsequently enlisted to produce the band's next album. Sessions were held at The Slaughterhouse recording studio in Driffield over three weeks. The period was noted for heavy drug use by the band and Hannett, with their manager later calling it the first "ecstasy-fuelled" album. Hannett moved recording to Strawberry Studios, where extra instrumentation was added. Bummed is a Madchester release described as "stiff psychedelic funk" by AllMusic. Much of the lyrical content on the album was influenced by the 1970 film Performance, with dialog from the film sampled throughout.

Happy Mondays toured the United Kingdom supporting James in late 1987, which coincided with the release of the lead single from Bummed, "Wrote for Luck", on 31 October 1988. Happy Mondays played a series of headlining shows to close out the year; stints of mainland Europe and the UK followed in the first half of 1989. "Lazyitis – One Armed Boxer", an alternative version of closing track "Lazy Itis", was released as the second single from the album on 6 May 1989. Following this, the band embarked on a North American tour supporting labelmates Pixies. At the suggestion of their manager, remixes of "Wrote for Luck" – retitled "W.F.L." – were made by Paul Oakenfold and Vince Clarke of Erasure. These versions were released together as part of a reissued "W.F.L." single in September 1989.

Bummed received generally positive reviews from music critics, many of whom praised Hannett's production work. It peaked at number 59 on the UK Albums Chart, though was initially seen as a disappointing seller by Factory Records. The original version of "Wrote for Luck" reached number seven on the UK Independent Singles Chart. "Lazyitis – One Armed Boxer" charted at number 46 on the UK Singles Chart, followed by the remixed "W.F.L." at number 68. Bummed appeared on album of the year and best of decade lists by NME and Sounds and Q. "Wrote for Luck" and Bummed have been viewed as defining releases of the acid house era and the Second Summer of Love.
