Defiance, Ohio is an acoustic punk rock band from Columbus, OH. They are named after the town of Defiance, Ohio. The band features a violin, cello, and double bass. They are known for their association with Plan-It-X Records, as well as anti-capitalist themes.

They have released four full length LPs, as well as a handful of split recordings. In the DIY spirit, much of their music is put out by the band themselves, producing their own CDs and CD-Rs, as well as allowing anyone to download all of their music for free from their website. When not releasing their own music, the band works with independent record labels in order to produce their releases. Typically these have been smaller independent labels. However, the band has worked with the more notable though still staunchly independent No Idea Records.
