Old Tennent Church is a Presbyterian church located at 450 Tennent Road in the Tennent neighborhood of Manalapan, New Jersey. The congregation was founded in 1692 and played a prominent role in the founding of Presbyterianism in America. The current edifice was completed in 1753 and was named in memory of pastors John Tennent and his brother William Tennent. The Old Tennent Cemetery is located on the same property.
The church itself is a historic Revolutionary War site. Patriots fought and won victory over the British close by in the Battle of Monmouth. The church building was used as a temporary hospital for wounded soldiers.
