American poet and teacher who was noted for his lyric verse and for his mentorship of aspiring poets.

Educated at the University of Minnesota, Dartmouth College (B.A., 1926), the University of Cambridge (B.A., 1929; M.A., 1933), and Harvard University, Eberhart published his first book of poems, A Bravery of Earth, in 1930. In the 1930s he also became tutor to the son of King Prajadhipok of Siam (now Thailand) and afterward taught at several American universities, particularly at Dartmouth (1956–71). In the early 1950s he helped found the Poet's Theatre in Cambridge, Massachusetts, to which he contributed verse dramas.

Eberhart combined a modern style with elements of Romanticism and frequently wrote about nature and death. His works include Collected Poems, 1930–1976 (1976; National Book Award), Of Poetry and Poets (1979), New and Selected Poems (1990), and a book of criticism. From 1959 to 1961 Eberhart was consultant in poetry to the Library of Congress (now poet laureate consultant in poetry). In 1962 he was cowinner, with John Hall Wheelock, of the Bollingen Prize for Poetry, and in 1966 he received a Pulitzer Prize for Selected Poems, 1930–1965 (1965). Eberhart's other honours include election to the American Academy of Arts and Letters in 1982.
