Ernest Howard Crosby (November 4, 1856 – January 3, 1907) was an American reformer, georgist, and author.

[4] While a member of the State Assembly (1887–1889), he introduced three high-license bills, all vetoed by the Governor David Bennett Hill.

[4] He became an exponent of the theories of Count Tolstoy, whom he visited before his return to America; his relations with the great Russian later ripened into intimate friendship, and he devoted himself in America largely to promulgating Tolstoy's ideas of universal peace.

His book, Plain Talk in Psalm and Parable (1899), was widely commended by such writers as Björnson, Kropotkin, and Zangwill.

[7] Like the Englishman Edward Carpenter, the subject of his book Poet and Prophet, Crosby's poetry (in the volume Swords and Plowshares) followed the example of Whitman's free verse.
