Saint Joseph College (セント・ジョセフ・カレッジ?) was a Catholic international school, located on the "Bluff" in Naka-ku, Yokohama, Japan. The school started as a division of Gyosei Gakuin in 1888 and was established as an independent school by the Marianists in 1901. St. Joseph closed with the graduating class of June 2000. It served kindergarten, elementary education and secondary education primarily to the expatriate community in Yokohama.
The school was the host to Japan's first Scout troop, established in 1911.
