Jindo (Korean: 진도) is the third largest island in South Korea. Together with a group of much smaller islands, it forms Jindo County.

In the Battle of Myeongnyang, on October 26, 1597, the Korean Joseon Kingdom's navy, led by Admiral Yi Sun-sin, fought the Japanese navy in the Myeongnyang Strait, near Jindo Island, off the southwest corner of the Korean Peninsula.
