"Tubthumping" is a song by British rock band Chumbawamba, released in August 1997 by EMI Records as the first single from their eighth studio album, Tubthumper (1997). Written and produced by the band, it is their most successful single, peaking at number two on the UK Singles Chart and topping the charts of Australia, Canada, Ireland, Italy and New Zealand. In the United States, it reached number six on the Billboard Hot 100 and topped three other Billboard charts. At the 1998 Brit Awards, "Tubthumping" was nominated for the Brit Award for Best British Single. It sold 880,000 copies in the UK.

The song was the group's lead single from Tubthumper, their major-label debut. It was released on 11 August 1997. Vocalist Dunstan Bruce retrospectively observed that, before the group wrote it, they "were in a mess: we had become directionless and disparate". He credited "Tubthumping" with changing that, telling The Guardian, "It's not our most political or best song, but it brought us back together. The song is about us – as a class and as a band. The beauty of it was we had no idea how big it would be."

A Leeds pub named the Fforde Grene served as the group's inspiration for the song. Guitarist Boff Whalley told The Guardian that it was written about "the resilience of ordinary people"; musically, "Tubthumping" is a dance-rock, alternative rock, and dance-punk song in D major. The intro to the song includes an excerpt from the British film Brassed Off.

In 2024, after the song was used by New Zealand politicians deemed to be anti-liberal, Whalley said, "Let me be clear: the song 'Tubthumping' was written to celebrate the resilience and tenacity of working-class folk who keep fighting when the chips are down. It has nothing whatsoever in common with wealthy politicians with extremist anti-liberal agendas. ...The right doesn't have any good songs. That's why they keep trying to nick ours."

In her trumpet solo, Jude Abbott interpolates the notable "Trumpet Voluntary", written by Jeremiah Clarke in about 1700.

The music video was directed by Ben Unwin. The video opens in a pub. The camera zooms past the clients, who appear to be frozen, and zooms in onto the small television on which the band are performing, dressed in black casual clothes, on a small stage in front of a red curtain which occasionally turns green. The video continues with the band appearing in the pub, intercut with shots of female clients applying make-up and chatting in the ladies' lavatory.

Larry Flick from Billboard magazine wrote, "Some records just demand attention: 'Tubthumping' is one of the rare few. You can spend three times the track's running time plucking out the seemingly disparate sounds and assorted genre references—starting with the forceful alterna-rock guitar scratches, the hip-hop-derived beats, and the swing-style horns. Holding it all together are the kind of rousing, gang-like chants that you hear at football games. Sounds odd, eh? Well, you won't soon forget this jam after first listen. And you'll likely be hearing it on pop and modern rock stations for months to come. If this gem is indicative of the tone of the act's forthcoming album, it should be quite a head trip." A reviewer from Daily Record described it as an "irritating catchy drinking anthem from the anarchist band". It was also named a "raucous anthem". Pan-European magazine Music & Media said, "After a decade and a half spent as indie heroes this collective is likely to break into the mainstream in a big way". Music Week gave the song a score of four out of five, noting that it "combines their unique sound with a very infectious chant that could have come from the terraces. Radio One's Simon Mayo has been heavily championing the song which should prove to be their biggest hit to date." Ian Hyland of the Sunday Mirror rated it eight out of ten, writing, "Sing a terrace chant, mention lager and the rugby boys will be making boozed-up human pyramids on the dance floor in seconds. And you'll have a monster hit – good work, chum." Troy J. Augusto from Variety named it a "drinking-and-dancing anthem" and "the quirk hit of the season".

In The Village Voice's Pazz & Jop poll for 1997, "Tubthumping" was voted the second-best single of the year. Australian radio station Triple J ranked it No. 3 in its Triple J Hottest 100 for the same year. Author Bruce Pollock included it in his 2005 book "The 7,500 Most Important Songs of 1944–2000". "Tubthumping" also placed at No. 12 in Rolling Stone's 2007 list of the "20 Most Annoying Songs" and at No. 8 in the magazine's 2011 list of the "Top 10 One-Hit Wonders of All Time". In 2017, Billboard ranked it No. 38 in their list of "The 100 Greatest Pop Songs of 1997".
