Wiryeseong (Korean: 위례성; Hanja: 慰禮城) was the name of two early capitals of Baekje, one of the Three Kingdoms of Korea.

According to Samguk Sagi (the oldest surviving Korean history book, written in the 12th century), Onjo, the son of Goguryeo's founder Jumong, founded the nation of Sipje (십제, 十濟; later became Baekje) on Wiryeseong in 18 BC, while his elder brother Biryu established himself in Michuhol (미추홀, 彌鄒忽) further to the west.

Later, Onjo moved further south because of Malgal to the north and Lelang to the east.

[3] During the Hanseong period, Baekje grew up against Southern Mahan and Northern Chinese Commanderies including Daifang, which attempted to violate their border.

Baekje's next king Munju moved south and set the new capital at Ungjin (modern day Gongju city).
