The Red Sun Band (styled as theredsunband) were a rock band from Sydney, Australia. For most of the band's run, it was composed of sisters Sarah (guitar, lead vocals) and Lizzie Kelly (keyboards, tambourine, backing vocals), as well as drummer John Matthews.

The band's sound was inspired by acts such as Mazzy Star and Cat Power, both for their production ethic and the treatment of the lead vocals. On the local front, the band received support from the numerous mid-late 1990s Australian bands who played a brand of atmospheric indie-rock informed by the shoegaze movement of the early 1990s, such as Sounds Like Sunset and Gersey, who gave the band their earliest support slots. The Red Sun Band played with such artists as Cat Power, Magic Dirt, Youth Group and The Panics, and were on the bill for the Big Day Out festival in both 2005 and 2009.
