Janggyeon Panjeon of Haeinsa, Buddhist temple complex in South Gyeongsang, South Korea.

Janggyeong Panjeon of Haeinsa consists of four wooden halls arranged around a rectangular courtyard behind the main hall: two long buildings, Sudara-jang to the south and Beopbo-jeon to the north, each 15 bays by 2, and two small halls of 2 by 2 bays. The long halls have hipped tile roofs, pale stone bases, and green lattice doors; the southern hall's facade alternates green-painted lattice panels with green-and-red patterned panels.

Haeinsa was founded in 802 under King Aejang of Unified Silla, according to tradition to thank the Buddha for curing a queen's illness. The temple burned several times, and the present main hall dates from 1817. The 81,352 printing blocks of the Tripitaka Koreana were carved from 1236 to 1251 on Ganghwa Island to seek Buddha's aid against the Mongol invasions, then moved to Haeinsa in 1398. The Janggyeong Panjeon was rebuilt in 1457 and newly constructed in 1488 by the monk Hakjo with royal support; it escaped the Imjin War fires and was repaired in 1622 and 1624.

The name Haeinsa means "ocean-seal," a Buddhist term for a mind clear and calm as the sea. The temple is called Beopbo-sa, "Dharma-jewel temple," because it holds the Tripitaka Koreana, one of the Three Jewels. The 81,352 woodblocks, carved from 1236 to 1251, are kept in the four halls of Janggyeong Panjeon, and visitors can see the blocks stacked on open shelves.

The two long halls, Sudara-jang to the south and Beopbo-jeon to the north, face each other across a rectangular courtyard, with the two small halls closing the east and west sides. The complex sits uphill behind the main hall, Daejeokgwang-jeon, so the approach is by foot on temple paths and steps. The buildings face southwest to catch sunlight.

Colonel Kim Young-hwan defied orders and halted the bombing of Haeinsa in 1951 during the Korean War; his memorial tablet is kept inside the Janggyeong Panjeon. The storehouse halls also sit apart from the walls, and their shelves stand about 30 cm above a floor layered with charcoal, lime, salt and sand.
