William Ashford (1746–1824) was an English painter who worked exclusively in Ireland, where he lived from the age of 18, having initially gone there to take up a post with the Ordnance Office. His earliest paintings were flower pieces and still lifes, but from 1772 he exhibited landscapes. He became president of the Irish Society of Artists in 1813, and was first elected President of the Royal Hibernian Academy. His works include a set of views in and around Mount Merrion, painted for the 4th Earl FitzWilliam.

Thomas Roberts was an Irish landscape artist.
