Robert Grenier (born August 4, 1941, in Minneapolis, Minnesota) is an American poet associated with the Language School.

Grenier's recent work, however, is as much visual as verbal, involving multicolor "drawn" poems in special (and not always reproducible) formats.

Ron Silliman, commenting on Robert Grenier's gesture some years afterward, wrote: Thus capitalized, these words in an essay entitled "On Speech," the second of five short critical pieces by Robert Grenier in the first issue of This, the magazine he cofounded with Barrett Watten in winter, 1971, announced a breach - and a new moment in American writing.
