Thomas Luny (1759 – 30 September 1837) was an English artist who primarily painted seascapes and other types of marine art.

There he became the apprentice of Francis Holman, a marine painter who would have a great and long lasting artistic influence on Luny.

Luny remained until 1780 in Holman's London studio, which was first situated in Broad Street, St. George's, and later relocated to Old Gravel Lane.

During this particular expedition, Luny almost certainly strayed from France itself; his first exhibited picture in London, seen at the Society of Artists that same year, was given the title A distant view of the island of Madeira and Porto Santo, suggesting that an engraving had inspired his choice of subject.

Similarly, it is unlikely that Luny was on hand for the Battle of the Nile in 1798 and the bombardment of Algiers in 1816, both of which he illustrated with dramatic atmosphere and credible realism.
