Habeas Corpus is a stage comedy in two acts by the English author Alan Bennett. It was first performed at the Lyric Theatre in London on 10 May 1973, with Alec Guinness in the central role. It ran, with cast changes, until 10 August 1974. The Broadway production that followed was less successful, running for less than three months. The play has been revived several times since then, in London and elsewhere.
