Authorities said the woman fell just after midnight on Sunday at Dwight Way and College Avenue.
Police said the 21-year-old woman from Elk Grove, California, likely fell from a third-story balcony.
She was breathing but unconscious when first responders arrived, and then died at the hospital, according to officials.
The woman was a student at UC Berkeley and was active in a sorority.
A witness told Eyewitness News sister station KGO-TV it appeared to be an accident. Police said their investigation was ongoing.
