Green Mind is the fourth studio album by alternative rock band Dinosaur Jr, released in 1991. It was the band's first release after bassist Lou Barlow's departure, as well as the first released by a major label. The record is close to being a J Mascis solo album, with drummer Murph only featuring on three tracks. 　　The cover photograph, Priscilla, 1969, is by Joseph Szabo and taken from his book of photographs Almost Grown.
