Peter Yu Tae-chol was a young Korean Catholic martyr who lived during the Joseon period. Born around 1826, he was the son of Augustine Nyou Tjin-kil, a government interpreter who was also martyred. During the Gihae persecution of 1839, the thirteen-year-old boy surrendered himself to the authorities. Following a period of physical abuse and torture involving hot coals, he was imprisoned and eventually strangled in Seoul.
