Rheostatics are a Canadian indie rock band. They were formed in 1978, and actively performed from 1980 until disbanding in 2007. After a number of reunion performances at special events, Rheostatics reformed in late 2016, introducing new songs and performing semi-regularly.

Although they had only one Top 40 hit, "Claire" in 1995, they were simultaneously one of Canada's most influential and unconventional rock bands, a band whose eclectic take on pop and rock music has been described both as iconic and iconoclastic. In particular, two of the band's albums, Whale Music and Melville, have been cited in numerous critical and listener polls as among the best Canadian albums ever recorded.
