The Toshima clan (豊島氏 or 豊嶋氏, Toshima-shi) was a Japanese samurai clan prominent in the Kamakura and Muromachi periods of Japanese history in the northwest of what is today Tokyo. The clan was based primarily in Shakujii castle, in what is today Shakujii Park in the town of Shakujii, in Nerima-ku, until the fall of the castle in the late 1470s to Ogigayatsu Uesugi clan vassal Ōta Dōkan.
