Portastatic is an American indie rock band founded in the early 1990s by Mac McCaughan. Portastatic began as a solo project for McCaughan, lead singer and guitarist of the indie rock band Superchunk. Since then it has evolved into a full-fledged band, which sometimes includes Superchunk guitarist Jim Wilbur and McCaughan's brother Matthew.

Tom Scharpling of 18 Wheeler fanzine (and later a popular DJ on WFMU) was so impressed by McCaughan's solo material that he cajoled him into releasing it under the fanzine's own imprint; so came 1993's "Starter" 7". Since then, under the Portastatic moniker, McCaughan has recorded several records drawing on a number of genres, including traditional indie rock, lo-fi, soundtrack and Brazilian music.
