Simon Episcopius was a Dutch theologian and Remonstrant who played a significant role at the Synod of Dort in 1618. His name is the Latinized form of his Dutch name Simon Bisschop.

The Remonstrants is a Protestant movement that split from the Dutch Reformed Church in the early 17th century. The early Remonstrants supported Jacobus Arminius, and after his death, continued to maintain his original views called Arminianism against the proponents of Calvinism. Condemned by the synod of Dort (1618–1619), the Remonstrants remained a small minority in the Netherlands. In the middle of the 19th century, the Remonstrant Brotherhood was influenced by the liberal Dutch theological movement.
