Thomas Jacques Somerscales (born in Kingston upon Hull on 29 October 1842; died 27 June 1927) was an English marine painter. He is also considered a Chilean painter as he began his career there and many of his landscapes evoke the region.
His father was a shipmaster, who sketched, and his uncle was an amateur painter. However he had no formal training as an artist and originally became a teacher in the Royal Navy. He also traveled around the Pacific and while teaching in Valparaíso he started working as a professional painter. By 1893 he was still referred to as a "little known artist" but had gained some praise.
His life's work has been detailed in the book: "Thomas Somerscales, Marine Artist" by Alex A. Hurst.
