John Boswell, American historian, philologist, and academic (d. 1994)
John Eastburn Boswell (March 20, 1947 – December 24, 1994) was an American historian and a full professor at Yale University. Many of Boswell's studies focused on the issue of religion and homosexuality, specifically Christianity and homosexuality. All of his work focused on the history of those at the margins of society.

His first book, The Royal Treasure: Muslim Communities Under the Crown of Aragon in the Fourteenth Century, appeared in 1977. In 1994, Boswell's fourth book, Same-Sex Unions in Pre-Modern Europe, was published. He died that same year from AIDS-related complications.
