Moses Harvey (March 21, 1820 – September 3, 1901) was an Irish-born Newfoundland clergyman, essayist and naturalist.

[2]Harvey studied many aspects of Newfoundland's natural history, most notably the habits of the giant squid.

[1][3] Harvey's interests in Newfoundland were varied: he had called for the creation of a cross-island railroad, he was president of the St. John's Athenaeum Society, he pressed for the development of mining in Newfoundland and he also catalogued the rocks, birds and wild flowers of the island.

His best-known and most prominent book was Newfoundland, The Oldest British Colony, which he co-authored with Joseph Hatton and published in 1883.

[3] Harvey served as Secretary to the Newfoundland Fisheries Commission and wrote and lectured a remarkable document entitled The Artificial Propagation of Marine Food Fishes and Edible Crustaceans, which was published in the Royal Society's transactions for 1892–1893 (volume 9).
