Pat Gerrard Cooke (4 June 1935 – 11 August 2000) was an English painter, illustrator and lifelong friend of artist LS Lowry (1887–1976). She is described as "one of the most commercially successful woman artists" of post-war Britain.
Born in Cheshire, with strong Irish heritage, she was mentored by Lowry from a child. She studied at the Manchester College of Art and the Slade School of Fine Art, London, teaching until 1965 and thereafter working full time as an artist. She relished painting the lives of everyday people: "the street, the pub, the cafe, the back alleys and the courtyards of Europe"; a great appreciator of Liverpudlian street life. She wrote three books and held dozens of sold out exhibitions across the UK and Ireland.
