In the early 1980s, Biafra collaborated with musicians Christian Lunch and Adrian Borland (of The Sound) and Morgan Fisher (of Mott the Hoople) for the electropunk musical project The Witch Trials, releasing one self-titled EP in its lifetime.

In 1988, Biafra, with Al Jourgensen and Paul Barker of the band Ministry, and Jeff Ward, formed Lard.
The band became yet another side project for Ministry, with Biafra providing vocals and lyrics.
According to a March 2009 interview with Jourgensen, he and Biafra are working on a new Lard album, which is being recorded in Jourgensen's El Paso studio.
 While working on the film Terminal City Ricochet in 1989, Biafra did a song for the film's soundtrack with D.O.A.. As a result, Biafra worked with D.O.A. on the album Last Scream of the Missing Neighbors.
Biafra also worked with Nomeansno on the soundtrack, which led to their collaboration on the album The Sky Is Falling and I Want My Mommy the following year.
Biafra also provided lyrics for the song "Biotech is Godzilla" for Sepultura's 1993 album Chaos A.D..
In 1999, Biafra and other members of the anti-globalization movement protested the WTO Meeting of 1999 in Seattle.
Along with other prominent West Coast musicians, he formed the short-lived band the No WTO Combo to help promote the movement's cause.
The band was originally scheduled to play during the protest, but the performance was canceled due to riots.
The band performed a short set the following night at the Showbox in downtown Seattle (outside the designated area), along with the hiphop group Spearhead.
No WTO Combo later released a CD of recordings from the concert, entitled Live from the Battle in Seattle.

As of late 2005, Biafra was performing with the band The Melvins under the name "Jello Biafra and the Melvins", though fans sometimes refer to them as "The Jelvins."
Together they have released two albums, and worked on material for a third collaborative release, much of which was premiered live at two concerts at the Great American Music Hall in San Francisco during an event called Biafra Five-O, commemorating Biafra's 50th birthday, the 30th anniversary of the founding of the Dead Kennedys, and the beginning of legalized same-sex marriage in California.
Biafra was also working with a band known as Jello Biafra and the Guantanamo School of Medicine, which included Ralph Spight of Victims Family on guitar and Billy Gould of Faith No More on bass.
This group debuted during Biafra Five-O.
In 2011, Biafra appeared in a singular concert event with an all-star cast of Southern musicians including members from Cowboy Mouth, Dash Rip Rock, Mojo Nixon and Down entitled, "Jello Biafra and the New Orleans Raunch & Soul All Stars" who performed an array of classic Soul covers to a packed house at the 12-Bar in New Orleans, Louisiana.
He would later reunite with many of the same musicians during the Carnival season 2014 to revisit many of these classics at Siberia, New Orleans.
A live album from the 2011 performance, Walk on Jindal's Splinters, and a companion single, Fannie May/Just a Little Bit, were released in 2015.
