Seong of Baekje (died 554) (r. 523–554) was the 26th king of Baekje, one of the Three Kingdoms of Korea. He was a son of Muryeong of Baekje and is best known for making Buddhism the state religion, moving the national capital to Sabi (present-day Buyeo County), and reclaiming the center of the Korean Peninsula. His demise eventually came at the hands of an ally who betrayed him.
