Kōfuku-ji (興福寺, Kōfuku-ji) is a Buddhist temple that was once one of the powerful Seven Great Temples in the city of Nara, Japan. The temple is the national headquarters of the Hossō school.

Kōfuku-ji has its origin as a temple that was established in 669 by Kagami-no-Ōkimi (鏡大君), the wife of Fujiwara no Kamatari, wishing for her husband’s recovery from illness. Its original site was in Yamashina, Yamashiro Province (present-day Kyoto). In 672, the temple was moved to Fujiwara-kyō, the first planned Japanese capital to copy the orthogonal grid pattern of Chang'an. In 710, the temple was dismantled for the second time and moved to its present location, on the east side of the newly constructed capital, Heijō-kyō, today's Nara.

Kōfuku-ji was the Fujiwara's tutelary temple, and enjoyed prosperity for as long as the family did. The temple was not only an important center for the Buddhist religion, but also retained influence over the imperial government, and even by "aggressive means" in some cases.[1] When many of the Nanto Shichi Daiji, such as Tōdai-ji, declined after the move of capital to Heian-kyō (Kyoto), Kōfuku-ji kept its significance because of its connection to the Fujiwara.

The temple was damaged and destroyed by civil wars and fires many times,[2] and was rebuilt as many times as well, although finally some of the important buildings, such as one of the three golden halls, the Nandaimon, Chūmon and the corridor were never reconstructed and are missing today. The rebuilding of the Central Golden Hall was completed in 2018.

Rokusō-an (六窓庵, Six Window Hut) was a chashitsu formerly located at the temple and considered one of the San-meiseki (三名席, Three Famous Tearooms).[3] It was relocated due its deteriorated state and is now in the gardens of the Tokyo National Museum.[4][5]
