Dr. Elias Root Beadle (1812–65) was an American clergyman. In addition to his success as a member of the Presbyterian priesthood, Beadle was famous as a scholar, particularly in mineralogy and the study of mollusk shells; he was considered an authority in the latter.
Born in Cooperstown, New York, Beadle became pastor of the First Presbyterian Church in Albion, New York, after graduating with a Doctor of Divinity. He then served as a missionary among the Druses of Mount Lebanon, Syria, and Constantinople (now Istanbul, Turkey.) He returned to establish three Presbyterian churches in New Orleans and served at the Pearl-street (Congregational) Church in Hartford, Connecticut, and the Second Presbyterian Church, Philadelphia.
