William Darling McKay (1844–1924) was a Scottish painter known for his atmospheric pastoral landscapes. Born in Gifford, McKay studied at the Trustees' Drawing Academy and Royal Scottish Academy School in Edinburgh. Influenced by the Dutch Hague School's en plein air method, he focused on capturing light and atmosphere in rural East Lothian. His works, often depicting men and women working the land, were widely popular. McKay became a member of the Royal Scottish Academy (RSA) in 1883 and contributed to Scottish art through publications and leadership roles. In later life, he served as Librarian and Secretary of the RSA. He passed away in 1924, leaving behind a significant artistic legacy.
