The Laughing Cavalier (1624) is a portrait by the Dutch Golden Age painter Frans Hals in the Wallace Collection in London. It was described by art historian Seymour Slive as "one of the most brilliant of all Baroque portraits". The title is an invention of the Victorian public and press, dating from its exhibition in the opening display at the Bethnal Green Museum in 1872–1875, just after its arrival in England, after which it was regularly reproduced as a print, and became one of the best known old master paintings in Britain.
