Austra is an electronic music project from Toronto, Ontario, founded by Katie Stelmanis in 2009. Katie writes and produces the music herself using Ableton Live. Maya Postepski, also a producer under the moniker Princess Century, sometimes contributes on the recordings. The music is performed live as a band with Maya Postepski on drums, Dorian Wolf on bass and Moog, and Ryan Wonsiak on keyboards. Austra used to include twin backing singers Sari and Romy Lightman of Tasseomancy.

Austra's debut album Feel It Break was released on May 11, 2011 by Domino Records and May 17, 2011 in Canada by Paper Bag Records. On July 6, 2011, the album was shortlisted for the 2011 Polaris Music Prize, but lost out to Arcade Fire's The Suburbs. Feel It Break was included on several year-end critics' lists; notably, both the Toronto Star and New York named it the best album of 2011, with the former calling it "an outright stunner". Stereogum named Austra a Band to Watch on March 14, 2011.

Their second album Olympia was released on June 18, 2013, from which the first single "Home" was released on March 7, 2013.
