Sir Walter Leaf (26 November 1852, Upper Norwood[1] – 8 March 1927, Torquay) was an English banker, classical scholar, and psychical researcher.

He published a benchmark edition of Homer's Iliad and was a director of Westminster Bank for many years, eventually becoming its chairman.

[4] He was concerned with uncovering the physical reality of the classical world, in contrast to the Cambridge Ritualists,[4] and was the foremost Homer scholar of his generation.

[4] Leaf also translated works from Russian and Persian, and was fluent in several European languages, including French, Italian, and German.

[9] It was his doctor who early in 1927 recommended him to visit Torquay, in the south-west of England, for the sake of his health.
