The Recognition of South Korea is the agreement that South Korea is a fully recognised sovereign state. The country was inaugurated in 15 August 1948, after the United States occupation of South Korea.

Later, The Philippines recognized that South Korea/ROK (Republic of Korea) was independent. After the recognition, North Korea invades South Korea. This led to the Korean War.
