Alfred Leslie Rowse, CH, FBA (4 December 1903 – 3 October 1997), known professionally as A. L. Rowse and to friends and family as Leslie, was a British historian from Cornwall. He is perhaps best known for his work on Elizabethan England and his poetry about Cornwall. He was also a Shakespearean scholar and biographer. He developed a widespread reputation for irascibility and intellectual arrogance.

Rowse was born in Tregonissey near St Austell, Cornwall, the son of Richard Rowse, a china clayworker, and Annie (née Vanson). His parents were poor and semi-illiterate but despite his origins, he won a place at St. Austell Grammar School (now Poltair School - who have named part of their curriculum the Rowse Pathway) and then a scholarship to Christ Church, Oxford in 1921. He was encouraged in his pursuit of an academic career by fellow Cornish man of letters, Sir Arthur Quiller-Couch, who lived at Polperro and who recognised his ability from an early age. Rowse had doubts about his paternity and paid particular attention to his mother's association with a local farmer and butcher from Polgooth, near St. Austell, Frederick William May (1872–1953).
