Samuel Miller (October 31, 1769 – January 7, 1850) was a Presbyterian theologian who taught at Princeton Theological Seminary.

From 1813 to 1849, he served as Professor of Ecclesiastical History and Church Government at Princeton Theological Seminary, and was also integral in founding the institution.

Miller is, perhaps, best known for the theological, polemical, and biographical writings he published throughout his life, including A Brief Retrospect of the Eighteenth Century (1803, 1805), Memoir of the Reverend John Rogers (1813), Letters on Unitarianism (1821), An Essay on the Office of the Ruling Elder (1831), The Primitive and Apostolical Order of the Church of Christ Vindicated (1840), Letters from a Father to a Son in College (1843), and Thoughts on Public Prayer (1849).
