Errol Lloyd (born 1943) is a Jamaican-born artist, writer, art critic, editor and arts administrator. Since the 1960s he has been based in London, UK, where he originally travelled to study law. Now well known as a book illustrator, he was runner-up for the Kate Greenaway Medal in 1973 for his work on My Brother Sean by Petronella Breinburg. Becoming involved with the Caribbean Artists Movement (CAM) in 1966, he went on to produce book jackets, greetings cards and other material for the London black-owned publishing companies, New Beacon Books, Bogle-L'Ouverture Publications, and Allison and Busby. Lloyd also had a long association with the Minorities' Arts Advisory Service (MAAS), whose magazine, Artrage, he edited for a while. He is recognised for having done much pioneering work for black art, beginning in the 1960s, when he was one of the few artists "who consciously chose to create Black images".
Eddie Chambers has written of him: "Gifted with an ability to capture likenesses in a range of creative and engaging ways, Lloyd has been responsible for a number of portrait commissions of leading Black and Caribbean males who have excelled in their respective fields over the course of the twentieth century", among them C. L. R. James, Sir Alexander Bustamante, Sir Garfield Sobers and Lord Pitt.
