Hyoseong (r. 737–742, died 742) was the 34th king to rule the Koreanic kingdom Silla. He was the second son of King Seondeok and Queen Sodeok.
Hyoseong took the daughter of the pajinchan Yeongjong as a concubine. This led to palace strife, as the jealous queen killed the concubine and Yeongjong plotted to kill her. Hyoseong had Yeongjong put to death.
After he died in 742, Hyoseong was cremated to the south of Beomnyusa temple, and his ashes were buried in the Sea of Japan (East Sea). Korean historians believe they had found what was believed to have been his planned tomb, but as Hyoseong died and was cremated this tomb was never finished.
