James Macdonald Barnsley (February 20, 1861–February 25, 1929) was a Canadian painter best known for his marine paintings and atmospheric landscapes. One of the earliest Canadian artists to achieve recognition in Paris, Barnsley exhibited at the Paris Salon and developed a style influenced by French naturalism, the Barbizon tradition, the Hague School and Impressionism. Although his active career lasted only about thirteen years, he became an important figure in late nineteenth-century Canadian art.

Barnsley was born in West Flamborough, near Dundas, Ontario. His early life was marked by tragedy, including the deaths of his father and sister and the destruction of the family paper mill by fire. He later moved with his mother to St. Louis, Missouri, where he studied at the St. Louis School of Fine Arts under Halsey C. Ives, Carl Gutherz and Paul E. Harney.

By late 1882, Barnsley had travelled to Paris to continue his artistic education. He studied with Luigi Loir and worked under or came into contact with Otto de Thoren, Félix de Vuillefroy and Raphaël Collin. During his years in France, Barnsley increasingly focused on the sea, ships, harbours and coastal subjects that would define his career. He exhibited in five Paris Salons, received favourable reviews and won awards at exhibitions in Versailles. He was also elected a member of the Société des Amis des Arts du Département de Seine-et-Oise.
Barnsley's marine paintings are noted for their strong sense of light, atmosphere and movement. His watercolours and some oil paintings show the subdued tonal influence of the Hague School, while other works display brighter colour and a freer, more Impressionistic handling. His subjects often included sailing ships, steam vessels, harbours, coastlines and European waterways.

Barnsley returned to North America in 1887 and established himself in Montreal while maintaining connections with New York. He exhibited with the Royal Canadian Academy of Arts and the Art Association of Montreal and showed his work through W. Scott & Sons Galleries. His paintings attracted important collectors, including Andrew Carnegie, who reportedly owned fifteen works. In 1889, Barnsley was appointed to teach at the Art Association of Montreal, where he worked within the same artistic circle as William Brymner and Maurice Cullen.
His career ended abruptly in 1892 when, at the age of thirty-one, he was admitted to the Protestant Hospital for the Insane in Verdun, Montreal. He never resumed painting professionally and remained institutionalized for most of the rest of his life. During the period surrounding his illness, Barnsley destroyed many of his paintings and drawings, making surviving examples comparatively rare.

His mother, Christina Barnsley, continued to promote his work after his career ended, helping place paintings in exhibitions and collections. Today, his work is represented in major Canadian institutions including the National Gallery of Canada, the Montreal Museum of Fine Arts and the Art Gallery of Hamilton.
