Pansy Division is an American queercore band formed in San Francisco, California, in 1991 by guitarist/singer/songwriter Jon Ginoli along with bassist Chris Freeman.

Conceived as the first openly gay rock band featuring predominantly gay musicians, Pansy Division's music, a mix of pop-punk and power pop, focuses mainly on LGBT issues, sex and relationships, often presented in a humorous light. In 1992, the band signed to punk label Lookout! Records and received international notoriety touring with Green Day in 1994, becoming the most commercially successful band of the queercore movement which began in the 1980s.

Pansy Division has released seven studio albums and three B-side compilations, among other recordings. In 2008, the band was the subject of a documentary film entitled Pansy Division: Life in a Gay Rock Band.

Frustrated by the lack of openly gay rock musicians, Jon Ginoli started performing solo sets under the moniker Pansy Division (a pun on Panzer division and a commonly used anti-gay slur "pansy") around San Francisco. Shortly after this, in 1991, Ginoli placed an ad in the San Francisco Weekly looking for "gay musicians into the Ramones, Buzzcocks and early Beatles". This caught the attention of Chris Freeman, who joined the band as a bassist. Ginoli and Freeman then recruited drummer Jay Paget, forming the first entirely out gay rock band that any of them had known. They hoped to defy the stereotype that gay men preferred pop divas and showtunes, by playing punk rock music.

Following extensive touring in California, several 7" singles and compilation appearances, Pansy Division signed to Lookout! Records, released their first album, Undressed in March 1993. They then embarked on their first national tour.

In 1994, with the release of their second album Deflowered and an appearance on Outpunk's seminal compilation Outpunk Dance Party, the band had proven themselves to be one of the more prolific and well-known artists to spring from the budding queercore movement. Catching the wave of pop-punk's mainstream explosion, Pansy Division were asked to tour with Green Day on the band's 1994 Dookie tour, introducing the group and queercore to a larger audience. During the tour's New York stop, the band caught the attention of Howard Stern, who met them backstage, and spent a segment talking about them on his nationally syndicated radio show.

While signed to Lookout!, the band continued to release an album every year. In 1995, Pansy Division released the album Pile Up notable for its various cover songs, included Ned Sublette's "Cowboys Are Frequently, Secretly Fond of Each Other" and Nirvana's "Smells Like Teen Spirit" (covered as "Smells Like Queer Spirit"). During their tour of eastern Canada in 1995, the band took a set of underwear shots in an old hotel, and produced a set of Pansy Division trading cards that were used as promotional materials for the next album. In 1996, the album Wish I'd Taken Pictures featured the single "I Really Wanted You". The music video for this single aired once on MTV. In 1997, the album More Lovin' From Our Oven collected a large number of B-sides that the band had already released as singles.

During this period, Pansy Division primarily performed as a trio, with Freeman and Ginoli being the only constant members amid a slew of perpetually rotating drummers, both gay and straight. In 1996, the band finally found a permanent gay drummer in the form of Luis Illades. In 1997, the band became a quartet with the addition of lead guitarist Patrick Goodwin.
