Glau was born in San Antonio, Texas, where she grew up with her two younger sisters Kaitlin and Christie. She is of Scots-Irish and German ancestry. Her mother is a schoolteacher, and her father a general contractor.

Glau received a scholarship to a ballet company and was homeschooled from grades 3 to 12 to accommodate her ballet training. She was classically trained as a ballet dancer and studied tango and flamenco. After a broken toe ended her dancing career, Glau moved to Los Angeles in 2002 to pursue acting.

Glau's first television credit was a guest role as a ballerina on a 2002 episode of the television series Angel. There she caught the eye of director Joss Whedon who later cast her in his critically acclaimed but short-lived TV series Firefly as River Tam, a role she reprised for the show's feature film sequel Serenity. Glau previously auditioned for the role of a Power Ranger (White Wild Force Ranger Alyssa Enrilé) in Power Rangers Wild Force but lost to actress Jessica Rey before meeting Whedon.

She also starred in the horror comedy film Mammoth. Glau was cast in the ABC Family TV movie The Initiation of Sarah.

In Terminator: The Sarah Connor Chronicles, a series that debuted January 13, 2008, Glau played the role of Cameron Phillips, a Terminator infiltration unit sent back to protect John Connor and Sarah Connor from Skynet. The series' seventh episode "The Demon Hand" included several scenes in which Glau (in character as Cameron) dances ballet and, Glau also played Allison Young (Cameron's human doppelgänger) in the episodes "Allison from Palmdale" and "Born to Run". Glau also guest starred as herself in a 2009 episode of the CBS situation comedy The Big Bang Theory.
