Good Clean Fun is a Posicore (positive hardcore) band from Washington, D.C..

Formed by four "Vegan Straightedge dudes" in 1997 because "the hardcore scene was in dire need of a sense of humor", this band uses self-irony when spreading their message of veganism, straight edge, and positivity. Their main influence is New York straight edge group Gorilla Biscuits, "We tried to sound as much like Gorilla Biscuits as possible." Other influences include 7 Seconds, Minor Threat, and Youth of Today.

The band recorded three records before parting way in 2002, saying "their mission had been accomplished and they reached for new goals." At the same time they released a compilation album from their entire career, Positively Positive 1997-2002, on Equal Vision. The band did a reunion tour in 2004 and released a brand new record in January 2006 entitled Between Christian Rock And A Hard Place, again on Equal Vision. In Europe their material is released by Reflections Records, and their new album will be accompanied by tours of Europe and the US.

They also released a limited edition split seven inch with Dead After School (UK hardcore, cat n cakey records) - a band that they met on tour in Iceland. they went on to tour together on their last UK tour.
