Nicholas Pocock (2 March 1740 – 9 March 1821) was a British artist known for his many detailed paintings of naval battles during the age of sail.
In 1778, Pocock's employer, Richard Champion, became financially insolvent due to the effects of the American Revolutionary War on transatlantic trade. As a result, Pocock gave up the sea and devoted himself to painting. The first of his works were exhibited by the Royal Academy in 1782.
Later that year, Pocock was commissioned to produce a series of paintings illustrating George Rodney's victory at the Battle of the Saintes. In 1789, he moved to London, where his reputation and contacts continued to grow. He was a favourite of Samuel Hood and was appointed Marine Painter to King George.
In addition to his large-scale oil paintings depicting naval battles, Pocock also produced many watercolours of coastal and ship scenes.
