Henry Peters Gray (June 23, 1819 - November 12, 1877), American portrait and genre painter, was born in New York.

He was a pupil of Daniel Huntington there, and subsequently studied in Rome and Florence. Elected a member of the National Academy of Design in 1842, he succeeded Huntington as president in 1870, holding the position until 1871.

The later years of his life were devoted to portrait work. He was strongly influenced by the old Italian masters, painting in mellow colour with a classical tendency. One of his notable canvases was an allegorical composition called "The Birth of our Flag" (1875). He died in New York City on the 12th of November 1877.
