Henry Moore RA RWS (7 March 1831 in York – 22 June 1895 in Margate) was an English marine and landscape painter.

He had a profound and scientific knowledge of wave-form, acquired at the cost of exposure in all weathers, and he was generally content to paint the sea itself without introducing ships or human figures.

He was a fine colourist, and held the foremost rank among English marine painters of his day.

Among the most remarkable of his Academy pictures are A White Calm (1858), The Launch of the Lifeboat (1876), now in the Walker Art Gallery, Liverpool, Cat's-paws off the Land, which was bought out of the funds of the Chautrey Bequest in 1885, and is now at Tate, The Clearness after Rain (1887), which won for the painter the grand prix and legion of honour at the Paris Exhibition of 1889, A Breezy Day in the Channel (1888), Shine and Shower (1889), Summer at Sea (1893), and Britannia's Realm (1880).

An exhibition of ninety pictures by Moore, entitled 'Afloat and Ashore,' was held by the Fine Art Society in 1887.
