Nerima Castle was a castle built around 1331-1333 by a branch of the Toshima Clan as a residence in their territory of Nerima. It once stood in what is now Toshima Amusement Park in Nerima City, Tokyo.

The castle was thought to have fallen in 1477 along with the Toshima main castle of Shakujii in the Battle of Egota-Numabukurohara when Oota Doukan of the Yamanouchi and Ougigayatsu Uesugi clans defeated Toshima Yasutsune, who had sided with Nagao Kageharu against the Uesugi clans in Nagao Kageharu's Rebellion in 1476.
