Daddy's Roommate is a children's book written by Michael Willhoite and published by Alyson Books in 1990. One of the first children's books to address the subject of homosexuality, the story follows a young boy whose divorced father now lives with his life partner. The book's depiction of a gay household has led to its inclusion in many educational programs, and Willhoite's work was awarded a Lambda Literary Award in 1991.

Due to the book's intended audience and the controversial topic of gay relationships, there have been numerous attempts to remove it from schools and libraries. Because of these attempts, it was the second-most challenged book in the United States from 1990 to 1999.
