Llangynwyd is a village (and electoral ward) 2 miles to the south of Maesteg, in the county borough of Bridgend, Wales.
The place name Llangynwyd refers to the hilltop village with a church dedicated to St Cynwyd, son of Cynfelyn.
All that remains of the original structure is the stone socket of a wooden cross, which can be seen in the wall above the entrance.
The old village of Llangynwyd, "Top Llan", was the home of the legendary Maid of Cefn Ydfa, featured in the song "Bugeilio'r Gwenith Gwyn".
The village still celebrates the New Year, or Calennig, with the Mari Lwyd: a horse's skull draped in a white sheet with flowers.
