Korguz (died 1242) was an Uyghur governor of Khorasan during the reign of the Mongol ruler Ogedei Khan. He began his career teaching Mongol children and thereafter assumed governorship of Khorasan. Originally a Buddhist, he converted to Islam later in his life. Korguz defied the family of the recently deceased Chagatai. For this reason, he was ordered to death by Töregene Khatun who directed that stones be stuffed into his mouth in public until Korguz fatally choked.
