Joseph William Comyns Carr (1 March 1849 – 12 December 1916) was an English drama and art critic, gallery director, author, poet, playwright and theatre manager.
Beginning his career as an art critic, Carr was a vigorous advocate for Pre-Raphaelite art and a vocal critic of the "short-sighted" art establishment.
In 1877 he became a director of the Grosvenor Gallery and promoting Pre-Raphaelite painters and other important exhibitors, such as James McNeill Whistler, Dante Gabriel Rossetti and Edward Burne-Jones.
Ten years later he founded the rival New Gallery.
Carr also wrote essays, books, plays, librettos, English-language adaptations of foreign works and stage adaptations of Dickens novels and classic tales like King Arthur and Faust.
