Asahel Nettleton (April 21, 1783 – May 16, 1844) was an American theologian and Evangelist from Connecticut who was highly influential during the Second Great Awakening. The number of people converted to Christianity as a result of his ministry was estimated by one biographer at 30,000.[1] He participated in the New Lebanon Conference in 1827, during which he and Lyman Beecher opposed the teachings of Charles Grandison Finney.[2]
