John Winebrenner (March 25, 1797 – September 11, 1860) was a Christian pastor, author and religious reformer who founded the Churches of God General Conference.

He studied at Dickinson College, Carlisle, Pennsylvania, and was ordained in the German Reformed Church in 1820.

In 1830, he and five other ministers founded the Church of God (whose members are sometimes called "Winebrennerians").

He served as speaker at the first eldership and subsequently edited and published the Church of God paper, first called The Gospel Publisher (1835–1845) and later The Church Advocate (beginning in 1845).

This opinion put him and his nascent denomination in accord with the Peace Churches movement in the United States.
