The Hyopgye Tae clan () is a Korean clan, with the bon-gwan (ancestral seat) based in Singye County, North Korea.
The apical ancestor of the clan is Tae Chungsang, the father of Tae Choyà Âng who founded Parhae. The intermediary ancestor () of the clan is considered to be (), a general of the Goryeo military regime and a descendant of Parhae's last crown prince, Tae Kwanghyà Ân. T'ae married his daughter to Ch'oe U, becoming the father-in-law of the de facto ruler of Goryeo. With the deaths of T'ae Chipsà Âng and Ch'oe U, Ch'oe U's illegitimate son, Ch'oe Hang, succeeded him. The T'ae clan fell out of power due to the transition, as Lady T'ae, the wife of Ch'oe U, supported Ch'oe U's grandson, Kim Mi (), not Ch'oe Hang, as the one to succeed her husband. With their fall from power, the T'ae clan moved out from the royal capital of Kaegyà Âng.
The 2000 South Korean census recorded the population of the clan as 1,348 members, belonging to 437 households.
