The House in Lordship Lane is a 1946 British detective novel by A.E.W. Mason. It is the fifth and final full-length novel in Mason's Inspector Hanaud series, published when the author was eighty-one. Unlike the others in the series the story is largely set in England, the Lordship Lane of the title being a thoroughfare in East Dulwich, South London.

Alfred Edward Woodley Mason was an English author and Liberal Party Member of Parliament. He is best remembered for his 1902 novel of courage and cowardice in wartime, The Four Feathers, and is also known as the creator of Inspector Hanaud, a French detective who was an early template for Agatha Christie's famous Hercule Poirot.
