Gerard Langbaine (15 July 1656 – 23 June 1692) was an English dramatic biographer and critic, best known for his An Account of the English Dramatic Poets (1691), the earliest work to give biographical and critical information on the playwrights of English Renaissance theatre. He is sometimes called Junior or the Younger to distinguish him from his father (1609–58) of the same name, a Doctor of Divinity who was Provost of The Queen's College, Oxford (1646–58) and Keeper of the University Archives.
