Robert Grenier (born August 4, 1941, in Minneapolis, Minnesota) is a contemporary American poet associated with the Language School. He was founding co-editor (with Barrett Watten) of the influential magazine This (1971–1974). This was a watershed moment in the history of recent American poetry, providing one of the first gatherings in print of various writers, artists, and poets now identified (or loosely referred to) as the Language poets.
