Didjits were an American punk rock band formed in Mattoon, Illinois in 1981, composed of Rick Sims on guitar/vocals, Doug Evans on bass, and Rick's brother Brad Sims, on drums. Didjits were known for the aggressive guitar playing and persona of Rick Sims, who often baited the audience between songs, and took plenty of abuse for it. Moreover, the band also added odd stunts and theatrical bits to some of their stage shows, particularly when playing in Chicago and Champaign.

They released their first album in 1986 on Bam Bam Records and disbanded in 1994, but briefly reunited in 2006. Brad Sims left the band in 1992. Former Scratch Acid drummer Rey Washam filled in for the Little Miss Carriage EP, and Todd Cole eventually took over as the drummer. Their song "Killboy Powerhead" was covered by The Offspring on their breakthrough 1994 album Smash.
