Thomas Alexander Boyd (July 3, 1898 – January 27, 1935) was an American journalist and novelist, born in Defiance, Ohio.

Boyd was raised by his mother's family due to his father's death before he was born.

While still in school, he and a friend enlisted in the U.S. Marine Corps and saw service in France during World War I, where he was gassed in 1918.

He opened a bookstore, Kilmarnock Books, in St. Paul, which became the locus of literary figures, including Sinclair Lewis.

[1] Boyd later remarried and became interested in Socialist causes during the Depression, eventually running as the Communist candidate for governor of Vermont.
