U.S. Chaos are an United States hardcore punk band from New Jersey, formed in early 1981.
Formed from the remainders of late 1970s punk rock group The Radicals, U.S. Chaos created one of the first legitimate streetpunk or Oi! style bands in The United States. The band was originally based in Passaic and Bergen counties, New Jersey. U.S. Chaos is the one of many punk bands of their time to author, produce, record as well as publish music with an ironic overzealous pro-American stance, both in lyrical content as well as attitude.
