William Conor OBE RHA PPRUA ROI (1881–1968) was a Belfast-born artist.
Celebrated for his warm and sympathetic portrayals of working-class life in Ulster, William Conor studied at the Government School of Design in Belfast in the 1890s. Born in the Old Lodge Road area of north Belfast, the son of a wrought-iron worker, his artistic talents were recognized at the early age of ten when a teacher of music, Louis Mantell, noticed the merit of his chalk drawings and arranged for him to attend the College of Art.
