Francis Turretin (17 October 1623 – 28 September 1687; also known as François Turrettini) was a Genevan-Italian Reformed scholastic theologian. Turretin is especially known as a zealous opponent of the moderate Calvinist theology of the Academy of Saumur (embodied by Moise Amyraut and called Amyraldianism). He was an earnest defender of the Calvinistic orthodoxy represented by the Synod of Dort, and as one of the authors of the Helvetic Consensus, which defended the formulation of predestination from the Synod of Dort and the verbal inspiration of the Bible.
