Portrait of William Linley is an oil on canvas portrait painting by the British artist Thomas Lawrence, from 1788. It depicts William Linley.
Lawrence was a young Bath-based society portraitist, just as his career was about to take off. The Linley Family of Bath were well-known musical performers, connected with the theatre. Lawrence was a friend of William Linley who was a year younger than him. The painting may have served as an audition for his bid for a royal commission. George III reputedly joked that Linley needed a haircut. Nonetheless, Lawrence was soon afterwards commissioned to paint the King's wife Queen Charlotte. That painting's success at the Royal Academy's Summer Exhibition led to Lawrence's establishment as a leading society portraitist. Today it is part of the collection at Dulwich Art Gallery in South London. It was given as part of a bequest by the painting's subject along with other works featuring his family.
