Lorenzo Thomas (August 31, 1944 – July 4, 2005) was an American poet and critic. He was born in the Republic of Panama and grew up in New York City, where his family immigrated in 1948. Thomas was a graduate of Queens College in New York. During his years there, he joined the Umbra Workshop, which drew young writers to the Lower East Side of New York City in search of their artistic voices. It served as a crucible for emerging black poets, among them Ishmael Reed, David Henderson and Calvin C. Hernton.
