George Harley was an English water-colour painter and drawing-master.

George Harley, born in 1791, appears as an exhibitor at the Royal Academy in 1817, when he sent two drawings of views in London. He had a large practice as a drawing-master, and drew in lithography some landscape drawings, as Lessons in Landscape, for Messrs. Rowney & Forster's series of lithographic drawing-books, published in 1820–2. In 1848 he published a small Guide to Pencil and Chalk Drawing from Landscape, dedicated to his past and present pupils, which reached a second edition.

Harley died in 1871, aged eighty, and was buried on the western side of Highgate Cemetery.
