Charles William Bartlett was an English painter and printmaker who settled in Hawaii.

Bartlett studied metallurgy and worked in that field for several years. At age 23, he enrolled in the Royal Academy in London, where he studied painting and etching. After three years of study in London, he entered the private studio school Académie Julian in Paris, where he studied under Jules Joseph Lefebvre (1836–1911) and Gustave Boulanger (1824–1888).

In 1889, he returned to England and married Emily Tate, but shortly thereafter, his wife and infant son died in childbirth. Bartlett then traveled to Europe, spending several productive years in the Netherlands, Brittany and Venice with his friend and fellow artist Frank Brangwyn (1867–1956). Brangwyn is believed to have introduced Bartlett to Japanese prints. Bartlett produced some of his most important early works on the Continent, especially studies of peasants painted in broad areas of colour. He was invited to join the Société Nationale des Beaux-Arts in France in 1897. In 1898, he returned to England and married Catherine "Kate" Main. Bartlett returned to the Continent with his second wife, and in 1908, he helped found the Société de la Peinture a l'Eau in Paris. Several Continental museums acquired his paintings at the Paris exhibitions of the Société de la Peinture a l'Eau.

Bartlett made several trips to Brittany and the Netherlands with the Dutch painter Nico Wilhelm Jungmann (1872–1935), which provided the former with material for future paintings of peasants, whose dignity derived from the simple placement of shapes.

In 1913, with financial backing from his wife's well-to-do family, the Bartletts traveled to India, Ceylon, Indonesia, China, and Japan. He arrived in Japan in 1915, where he met woodblock print publisher Watanabe Shōzaburō (1885–1962), who was a major force in early 20th-century Japanese art (shin-hanga). In 1916 Watanabe published 21 woodblocks from Bartlett's designs, including six prints of Japanese landscapes. In 1917, Bartlett and his second wife left Japan for England; however, they stopped off in Hawaii, where they remained—never returning to England. He did visit Japan in 1919, where he created sixteen shin-hanga prints for Watanabe.

Anna Rice Cooke (1853–1934), who founded the Honolulu Museum of Art, became Bartlett's advocate and patron. In 1928, Bartlett helped to found the Honolulu Printmakers along with local artists Alexander Samuel MacLeod, John Melville Kelly, and Huc-Mazelet Luquiens. Charles Bartlett died in Hawaii at the age of 79 on 16 April 1940.
