Regurgitator are an Australian alternative rock band from Brisbane, Queensland, formed in late 1993 by Quan Yeomans on lead vocals, guitar and keyboards; Ben Ely on bass guitar, keyboards and vocals; and Martin Lee on drums. Their debut studio album, Tu-Plang was released in May 1996; it was followed by Unit in November 1997 which was certified triple platinum. Unit won five categories at the ARIA Music Awards of 1998: Album of the Year, Best Alternative Album, Producer of the Year (for Magoo), Engineer of the Year (Magoo) and Best Cover Art (for The Shits). Their third album, ...Art was released in August 1999.

Regurgitator had two singles reach the top 20 with "Polyester Girl" (May 1998) peaking at No. 14 in Australia and No. 16 in New Zealand; while "Happiness (Rotting My Brain)" (July 1999) also appeared at No. 16 in New Zealand. Martin Lee left Regurgitator in late 1999 and was replaced by Peter Kostic on drums, who was simultaneously a member of Front End Loader (1991–present) and the Hard-Ons (2002–2011). Casual members have included Seja Vogel, from Sekiden; Shane Rudken (Ponyloaf); Dave Atkins (Pangaea, Resin Dogs) among others. Regurgitator's fourth studio album, Eduardo and Rodriguez Wage War on T-Wrecks was released in July 2001 and was their final studio album for Warner before mutually agreeing to terminate their recording agreement. They then went on to issue four more independent studio albums—Mish Mash! recorded as part of the multimedia reality show parody Band in a Bubble; Love and Paranoia recorded in Rio de Janeiro on Corcovado after licensing the Band in a Bubble project to a US version staged in New York City; Super Happy Fun Times Friends recorded over three weeks in their home studio; and Dirty Pop Fantasy recorded in a Hong Kong apartment before announcing an extended hiatus in December 2013. They commenced playing shows again in mid-2015. Recording at 'Greg's Byron Bay & Wild Mountain Sound resulted in ninth album Headroxx released in 2018. In 2022 work began on new music which came to be Invader released April 2024.

The group's spin-off project Regurgitator's Pogogo Show released their debut album of children's music in 2019.

Regurgitator was originally a 3-piece indie rock band with Quan Yeomans (guitar and vocals), Ben Ely (bass and vocals) and Martin Lee (drums). The three had purportedly met on a bus in inner Brisbane. At this time, all three were already in several bands - Pangaea, Zooerastia, Precision Oiler, Brazilia among others. Regurgitator at this time was not considered to be the main focus of any members, rather as a side-project to their other bands.

The band released its debut self-titled EP in October 1994. With the emergence of Brisbane's underground music scene in the early 1990s, major labels, such as Warner Music Group, took the initiative to expand its Australian music roster. A&R representative Michael Parisi initially pursued Pangaea, a popular and established band in Brisbane's underground that Ben Ely fronted. It wasn't until Parisi was supplied with Pangaea recordings by their manager Paul Curtis that he discovered Regurgitator, whose material was also presented as part of a potential Valve label P&D deal. Ironically, Parisi would push for the less-established band to be signed because "it was the hook that Pangaea, for all the excitement [it] had generated on stage, had lacked."

The band signed with Warner early in 1995, who re-released its debut EP in February 1995, which charted at number 45 on the ARIA singles chart. Regurgitator quickly released another EP, titled New, which featured radio hits "Track 1" and "Blubber Boy". New peaked at number 30 on the ARIA singles chart.

Following the success of their first two EPs, the band made an unusual move by travelling to Thailand to record their first full-length album. Made on a comparatively small budget at a famed pop studio in Bangkok, Tu-Plang (ตู้เพลง; Thai for 'Jukebox'), largely featured a mixture of rock and hip hop, which was particularly evident on its third single release "Kong Foo Sing". The band also experimented in a number of genres including techno, musak, surf rock and dub. Yeomans gained notoriety for his uniquely cynical and obscene lyrical style, most notably the controversial pop-rock tune "I Sucked a Lot of Cock to Get Where I Am", which was attacked by Australian radio identity Alan Jones, who campaigned to have it removed from airplay. Tu-Plang peaked at number 3 on the ARIA Charts, was certified platinum and won Best Alternative Release and Breakthrough Artist at the ARIA Music Awards of 1996.

The band recorded their second studio album in a warehouse in Brisbane which they affectionately named "The Dirty Room". In contrast with their rock-oriented works of the past, the band moved on with a more electronic and pop based sound. The band openly acknowledged their stylistic change with the album's opening track, ironically titled "I Like Your Old Stuff Better Than Your New Stuff". The band released "Everyday Formula" as the first single, with Yeomans and Magoo later admitting it was a conscious decision to ease their fans into the new sound with a heavier track. The single release in October 1997 peaked at number 41 on the ARIA Charts. Unit was released in November and peaked at number 4 on the ARIA Charts. "Black Bugs", "Polyester Girl" and "! (The Song Formerly Known As)" (an homage to 1980s era Prince) were all released as singles and gained significant amounts of airplay. Unit is Regurgitator's most commercially successful album, going platinum three times in Australia. Whilst it no doubt increased the popularity of the band, fans of their first generation of work are still divided in their responses to it.
