Benjamin Elbel (16 March 1690 – 4 June 1756) was a German Franciscan moral theologian.
He belonged to the Strasburg Franciscan province, was lector of theology, and held high positions in the order.
His major work, "Theologia moralis decalogalis et sacramentalis" (Venice, 1731), passed rapidly through several editions.
A new edition was prepared by Irenaeus Bierbaum, under the title "Theologia moralis per modum conferentiarum auctore clarissime P. Benjamin Elbel..." (3 vols., Paderborn, 1891–92).
He applied abstract principles to strikingly practical cases, and his approach proved influential.
