Prince Koreyasu (惟康親王, Koreyasu Shinnō, 26 May 1264 – 25 November 1326; reigned 1266 – 1289), also known as Minamoto no Koreyasu (源 惟康), was the seventh shōgun of the Kamakura shogunate of medieval Japan.

[1] He was the nominal ruler virtually controlled by the Hōjō clan regents.

At age 25, the deposed shōgun became a Buddhist monk.

His priestly name was Ono-no miya.

[1] The years in which Koreyasu is shogun are more specifically identified by more than one era name or nengō.
