The Battle of Yeongpyeong (or Second Battle of Yeonpyeong) (Korean: 제2 연평해전, Je I(2) Yeonpyeong Haejeon) was a confrontation at sea between North Korean and South Korean patrol boats along a disputed maritime boundary near Yeonpyeong Island in the Yellow Sea in 2002. This followed a similar confrontation in 1999. Two North Korean patrol boats crossed the contested border and engaged two South Korean Chamsuri-class patrol boats. The North Koreans withdrew before South Korean reinforcements arrived.
