Aus-Rotten was an American crust punk band formed in Pittsburgh, Pennsylvania. Active from 1991 to 2001, its members practiced and promoted a philosophy of anarchist politics. The band included lead vocalist Dave Trenga, vocalist/guitarist Eric Good, bassist Corey Lyons, and drummer Matt Garabedian. Spitboy singer Adrienne Droogas would often join the band in their later material.

The band’s 1994 Fuck Nazi Sympathy 7 sold 25,000 copies, making it Havoc Records’ best-selling release. Fuck Nazi Sympathy topped a list of bestselling D.I.Y. Punk record label releases compiled in 2008

Aus-Rotten went on a hiatus in the mid-‘90s and during that time Dave formed Human Investment with Andy of Anti-Flag and Corey and Eric formed Doomsday Parade. Aus-Rotten broke up for good in early 2001 and members have gone on to form Caustic Christ and Behind Enemy Lines.

On August 18, 2019 Aus-Rotten performed a few songs at Skull Fest 11 in Pittsburgh.

The band’s name comes from the German verb ausrotten, which translates to “exterminate” or “eradicate”.
