Julien Baker (born September 29, 1995) is an American singer-songwriter and guitarist from Memphis, Tennessee. She is a member of the alternative rock band, Forrister, formerly called The Star Killers.

During her freshman year at Middle Tennessee State University, Baker separated from Forrister and began writing songs on her own, eventually self-releasing an EP in the winter of 2014 on Bandcamp, which would become the studio album Sprained Ankle, released in October 2015.

She is also one third of the indie rock super-group boygenius, formed in 2018 with fellow singer-songwriters Phoebe Bridgers and Lucy Dacus.
