Francis Swaine (1725–1782) was a British marine painter. He was born in 1725, and christened on 7 October of that year at St Dunstan's, Stepney, London. His parents were named Francis Swaine and Ann Joel. In 1735 the elder Francis Swaine, the marine painter's father, applied in writing to the Commissioners of His Majesty's Navy for employment as a Navy Messenger, in succession to Mr William Wyatt. He mentions that he had served "upwards of twenty eight years" in the Navy, and that his father had died Purser of the Royal Katherine. He mentions also that he had carried out "little labours in drawing", and that he at that time had five small children. The first-born of these children was the Francis Swaine who became the marine painter. The elder Swaine was duly employed as a Navy Messenger.
