Yi Ŏkki (Korean: 이억기; Hanja: 李億祺; 3 September 1561 – 27 August 1597) was the commander of the Korean Eastern Jeolla Fleet and later came to be the commander of the Western Jeolla Fleet. At age 32, despite being 15 years younger than Supreme Naval Commander Yi Sun-sin, Yi Ŏkki became his most trusted commander and companion during the Seven Year War. Yi Ŏkki was eventually killed in the devastating Battle of Chilcheollyang Strait while assisting Wŏn Kyun, the Naval Commander of the entire Korean navy at that time while Yi Sun-sin was imprisoned as a result of a plot.
