Lullabies of Broadmoor: A Broadmoor Quartet is a set of four plays by English writer Steve Hennessy, which received its London premiere at the Finborough Theatre in 2004. It returned to that theatre in 2011 after runs at the Corner House in Frome, the Alma Tavern Theatre in Bristol and the Edinburgh Fringe earlier in 2011. As the title suggests, they all deal with prisoners and staff of Broadmoor and the victims of the prisoners' crimes.
