Friedrich Heinrich Ranke (30 November 1798, Wiehe – 2 September, 1876 Munich) was a German Protestant theologian. He was the brother of historian Leopold von Ranke (1795–1886) and the father of pediatrician Heinrich von Ranke (1830-1909) and anthropologist Johannes Ranke (1836-1916).
He studied theology and philology at the University of Jena, where he was a pupil of Heinrich Luden and Johann Philipp Gabler. He then studied philosophy at the University of Halle (from 1817), afterwards working as a private schoolteacher in Frankfurt an der Oder. In 1826 he was named pastor in the town of Rückersdorf.
In 1834 he relocated to Thurnau as dean and senior pastor, and several years later was appointed professor of theology at the University of Erlangen as a successor to Hermann Olshausen (1840). In 1842 he was appointed Konsistorialrat in Bayreuth, followed by duties as Konsistorialrat and Hauptprediger in Ansbach. In 1866 he was appointed Oberconsistorialrat in Munich.
He wielded considerable influence towards the implementation of the Erweckungsbewegung (revivalist movement) in Bavaria. He also promoted the development of the Innere Mission (German evangelical movement). Ranke was an opponent of theological rationalism.
