Sir Peter Lauderdale Daubeny, CBE (16 April 1921, Wiesbaden, Germany – 6 August 1975, London) was a British theatre impresario. Daubeny trained with Michel Saint-Denis and began his career under the director William Armstrong at the Liverpool Playhouse. Losing his left-arm at Salerno in 1943 led to him abandoning an acting career and staging his own productions including Franz Werfel's Jacobowsky and the Colonel in 1945. The London visits of the Berliner Ensemble in 1956 and the Moscow Art Theatre were organised by Daubeny.
