Bongwonsa, Buddhist temple in Seodaemun District, Seoul, South Korea.

Bongwonsa is a Korean Buddhist temple located at the base of Ansan Mountain, featuring multiple halls and structures arranged within the temple grounds. The main Buddha Hall underwent reconstruction in 1994 and serves as the religious center of the complex.

Founded in 889 by Master Doseon as Banyasa, the temple stood on the site of today's Yonsei University. King Yeongjo moved it to the foot of Ansan in 1748 and gave a plaque in his own hand, lost in the Korean War. In the late 19th century monk Lee Dong-in met reformists such as Kim Ok-gyun here.

Yeongsanjae, a Buddhist rite with traditional music and dance, is performed each year at Bongwonsa; the temple keeps the Yeongsanjae Preservation Society and the Okcheon Beomeum College to train younger monks. The rite is listed as Important Intangible Cultural Property No. 50, with Kim In-sik (monastic name Guhae) as holder of the beompae chant.

To reach the temple, take Line 2 to Sinchon Station and exit at Exit 3, then board Bus 7024 to the final stop. From there, a walking path leads uphill to the temple grounds.

The garden holds 16 white Arhat statues, enlightened beings who may choose to guide others. The temple is also where, in summer 2004, around eleven bodies buried by serial killer Yoo Young-chul were found nearby.
