Negoro-ji (根来寺) is a Buddhist temple located in the city of Iwade, Wakayama Prefecture in the Kansai region of Japan. Surrounded by the sacred peaks of the Katsuragi Mountains, the temple grounds were designated as a National Historic Site and a National Place of Scenic Beauty in 2007.

Buddhist temples or monasteries are the most numerous, famous, and important religious buildings in Japan. The shogunates or leaders of Japan have made it a priority to update and rebuild Buddhist temples since the Momoyama period. The Japanese word for a Buddhist monastery is tera (寺), and the same kanji also has the pronunciation ji, so temple names frequently end in -dera or -ji. Another ending, -in (院), is normally used to refer to minor temples. Examples of temple names that have these suffixes are Kiyomizu-dera, Enryaku-ji and Kōtoku-in.
