The Irresistible Grace Calvinist Church is an abandoned church that stands atop Galloway Hill in Prophecy Creek, Pennsylvania.

The Church has been abandoned since Christmas of 1928, after 39 parishioners died from tetrodotoxin poisoning.

On 7 August 2013, the body of Jeremy Richter was found in the Church, having died of apparent self-inflicted aconitum poisoning.
