William Morris (1834 – 1896) was an English textile designer, poet, artist, writer, and socialist activist associated with the British Arts and Crafts movement. He was a major contributor to the revival of traditional British textile arts and methods of production. His literary contributions helped to establish the modern fantasy genre, while he helped win acceptance of socialism in fin de siècle Great Britain.

Morris is recognized as one of the most significant cultural figures of Victorian Britain. He was best known in his lifetime as a poet, although he posthumously became better known for his designs. The William Morris Society founded in 1955 is devoted to his legacy, while multiple biographies and studies of his work have been published. Many of the buildings associated with his life are open to visitors, much of his work can be found in art galleries and museums, and his designs are still in production.
