The 13th Floor Elevators was an American rock band from Austin, Texas, formed by guitarist and vocalist Roky Erickson, electric jug player Tommy Hall, and guitarist Stacy Sutherland, which existed from 1965 to 1969. During their career, the band released four LP records and seven 45s for the International Artists record label.

They are often credited as one of the first psychedelic bands in the history of rock n' roll. According to the 2005 documentary You're Gonna Miss Me, Tommy Hall is credited with coining the term "psychedelic rock", although artists such as the Holy Modal Rounders and the Deep had used the term "psychedelic" to describe their music earlier. Their contemporary influence has been acknowledged by 1960s musicians such as Billy Gibbons of ZZ Top, Peter Albin of Big Brother and the Holding Company, and Chris Gerniottis of Zakary Thaks.
