The Joseon naval campaigns of 1592 were naval campaigns conducted by Korean admiral Yi Sun-sin during Japanese invasions of Korea (1592-1598) against the Japanese forces of Toyotomi Hideyoshi. These campaigns made Yi a legendary figure in Korean history on par with, if not surpassing, the great general Eulji Mundeok. The campaigns of Yi were vital in halting the Japanese invasion, which had the ultimate aim of conquering not just Korea, but Ming China as well. Yi was able to severely impair Japanese logistics and reinforcements for the land forces in Korea.
