Sekkei-ji Temple, Buddhist temple in Kōchi, Japan

Sekkei-ji is a Rinzai Zen temple in Kōchi, Shikoku, with a long single-story hall under a broad grey tiled roof and, to its right, a taller entrance with upturned eaves. Dark timber facades, blue banners and a hanging blue curtain face a gravel forecourt. The main hall was rebuilt in 2004.

Founded by Kukai as Shourinsan Koufukuji, the temple was renamed Keiun-ji in the Kamakura period. It fell into ruin, then in the late Tensho era (1573–1593) the priest Geppo revived it as a Rinzai Zen temple with backing from Chosokabe Motochika. After Motochika's death in 1599 it became the Chosokabe family temple, and its name Sekkei-ji comes from his posthumous title, Sekkei Jozan.

The temple is the 33rd stop on the Shikoku Pilgrimage, and pilgrims in white often leave handwritten sutra copies at the office. The temple's name comes from the posthumous title of Chosokabe Motochika, whose family made it their burial temple. A haiku stone by Basho stands to the right of the Daishi hall.

Sekkei-ji stands in the Nagahama district of Kōchi, about 300 m from the Nagahama bus stop on the Tosaden lines to Nagahama and Katsurahama, and roughly 100 m from the Sekkei-ji-mae stop on Route 278. The grounds are entered through a stone pillar gate, with the bell tower on the right and the water basin on the left; the main hall is straight ahead and the Daishi hall to its right. Parking holds 10 cars and 5 large vehicles. Lodging is possible in the tsuyadō by asking at the nōkyō office.

The temple's name comes from the posthumous Buddhist name of Chosokabe Motochika, "Sekkei Jozan Daizenmon". After the anti-Buddhist movement of 1870 closed the temple, a shrine was built on the site of its main hall the following year, enshrining a seated statue of Motochika as its kami. The temple was revived in 1879 by the monk Daigen on the site of the former Ishin-kan.
