Toghtua Bukha (Middle Mongolian: ᠲᠣᠭᠲᠠᠬᠤ ᠪᠤᠬᠠ; Toγtoγa Buqa; died 1376), also Toqto'a-Buqa, was a member of the House of Wang of the Goryeo dynasty.
Empress Öljei Khutugh and her son, Crown Prince Ayushiridara (Emperor Zhaozong of Northern Yuan) tried to replace Gongmin of Goryeo because he had exterminated the Ki family in 1356.
Yi Inim's faction finally installed Wang U as Goryeo king but the Northern Yuan dynasty (rump state of the Yuan dynasty) attempted to appoint Toghtua Bukha.
Toghtua Bukha's activity during this strife is almost unknown, but he seems to stayed in Naghachu's camp in Manchuria and watched for a chance.
