Andreas Osiander (19 December 1498 – 17 October 1552) was a German Lutheran theologian.

Born at Gunzenhausen, Ansbach, in the region of Franconia, Osiander studied at the University of Ingolstadt before being ordained as a priest in 1520 in Nuremberg. In the same year he began work at an Augustinian convent in Nuremberg as a Hebrew tutor. In 1522, he was appointed to the church of St. Lorenz in Nuremberg, and at the same time publicly declared himself to be a Lutheran. During the First Diet of Nuremberg (1522), he met Albert of Prussia, Grand Master of the Teutonic Knights, and played an important role in converting him to Lutheranism. He also played a prominent role in the debate which led to the city of Nuremberg's adoption of the Reformation in 1525, and in the same year Osiander married.

Osiander attended the Marburg Colloquy (1529), the Diet of Augsburg (1530) and the signing of the Schmalkalden articles (1531). The Augsburg Interim of 1548 made it necessary for him to leave Nuremberg, settling first at Breslau (Wrocław), then, in 1549, at Königsberg (Kaliningrad) as professor of the newly founded Königsberg University, appointed by Albert of Prussia. Osiander lived and worked in Königsberg until his death in 1552. Osiander's son Lukas (1534–1604), and grandsons Andreas (1562–1617) and Lukas (1571–1638) also worked as theologians. His niece married the future Archbishop of Canterbury, Thomas Cranmer.
