Lady Yocun (ヨンクン, Yonkun^?) is a non-player character from Final Fantasy X. She was a member of the Crusaders and later High Summoner of Spira in Final Fantasy X. She often trained outside the Cavern of the Stolen Fayth.

Lady Yocun is mentioned several times by members of the Crusaders, who hold her in high regard. She is seen in a memory generated by the pyreflies in the Zanarkand Dome, with a Guardian who offers to become her Final Aeon. An outline of her concept art decorates the Unerring Path Garment Grid in Final Fantasy X-2.
