Vadakkankulam is a small town in Radhapuram Taluka, Tirunelveli District of Tamil Nadu state, India. It was the home of S. A. Raja. Notable attraction is the Holy Family Church, which was built in 1779.

St. John de Britto who was on horse journey accosted the four Catholic families here who had come from the village of Thoppuvilai in 1600. He built a small thatched church dedicated to the Holy family in 1605. As many Catholic families from elsewhere settled down here, it became part of Nemam mission belonging to the Jesuit province of Cochin.
