Kōtoku-in (高徳院) is a Buddhist temple of the Jōdo-shū sect, in the city of Kamakura in Kanagawa Prefecture, Japan. Its mountain name is Taiizan (大異山), and its common temple name is Shōjōsen-ji (清浄泉寺).

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.
