King Chaekgye of Baekje (?-298, r. 286-298) was the 9th king of the Korean Baekje kingdom, one of the Three Kingdoms of Korea. His wife, whose name is recorded as Bo-Gwa (보과, 寶菓), was a daughter of the governor of Daifang commandery. This marital alliance contributed to friction between Goguryeo and Baekje, after Goguryeo attacked Daifang in 286 and King Chaekgye sent troops to Daifang's aid. King Chaekgye fortified the Acha Mountain Fortress and Sa Castle to defend the Han River valley against expected retaliation.
In 298, Baekje was invaded by Dongye and the Lelang commandery, and King Chaekgye was slain.
