Hannah was born in Chicago to Susan Jeanne Metzger and Donald Christian Hannah, whose tugboat and barge company provided her family background.

Parker School in Chicago before studying ballet and acting at the University of Southern California, making her film debut at age 17 in Brian De Palma's The Fury (1978).

Hannah married Canadian-American musician Neil Young in July 2018 after beginning their relationship in 2014. She previously dated several notable figures including John F. Kennedy Jr., Val Kilmer, and Jackson Browne. Hannah has no children and is not a twin, despite frequent online speculation. A lifelong environmental activist, she became vegan at age 11 after meeting a calf destined for slaughter, drives a biodiesel vehicle, and was arrested in 2006 while protesting the demolition of a community farm in Los Angeles.
