Bob Grumman (February 2, 1941 – April 2, 2015) was an American mathematical poet and critic of what he called "otherstream" poetry.

Born in Norwalk, Connecticut, he lived for around 15 years in North Hollywood, California, before moving to Port Charlotte, Florida.

He served in the U.S. Air Force as a Medic during the Vietnam War from 1960 to 1964, and was a member of the USAF Tennis Team.

[2] He worked as a substitute teacher for 14 years starting in late 1994, mainly at Charlotte High School.

His essay "MNMLST poetry: Unacclaimed but flourishing" explored the subtleties in very compressed poems such as Aram Saroyan's single word works.
