King Muryeong (무령왕; 武寧王; 462-523 r. 501-523) was the twenty-fifth king of Baekje during the period of the Three Kingdoms of Korea.

He was born in a small island of Japan when his mother was sent as a hostage to Japan. They were sent back to Baekje. He was called Semakishi (嶋君) and King Shima (斯麻王) in Japanese books. His father differs among historical sources.

He was important for stabilizing his realm so that it could experience a renaissance under his successor, King Seong. In 1971, Munyeong's tomb was excavated in the Korean city of Gongju.
