Heungnyunsa (Korean: 흥륜사; Hanja: 興輪寺) was an ancient Buddhist temple that was recreated in Gyeongju, South Korea.

However, a roof tile later discovered in that area has led some scholars to argue that it actually hosted a different former temple Yŏngmyosa.

[3][4] The temple was said to have been founded by Buddhist monk Ado [ko], the first person to bring Buddhism to Silla.

In 544, Buddhism was made the state religion, and King Jinheung gave the temple permission to operate.

One notable relic found in this area was the Roof-end Tile with Human Face Motif,[1] which was purchased by a Japanese person from a Gyeongju antique shop in 1934.
