Titian Ramsay Peale (November, 1799 - March 13, 1885) was an American artist and naturalist. He was the son of Charles Willson Peale.

Peale took part in the 1817 expedition of the Academy of Natural Sciences to Florida and Georgia, together with Thomas Say, George Ord and William Maclure. He was assistant to Say on the expedition to the Rocky Mountains led by Stephen Harriman Long in 1819. The collection submitted to the Academy of Natural Sciences in Philadelphia from this expedition included 122 drawings by Peale.

Peale provided illustrations for Say's American Entomology (1824-28) and Charles Lucien Bonaparte's American Ornithology (1825-33). He also undertook a collecting expedition to Florida on behalf of Bonaparte.

Peale also took part in the Pacific expedition led by Charles Wilkes between 1838 and 1842. Peale's report of the trip, Mammalia and Ornithology (1848), was suppressed due to objections by Wilkes.
