Yeosu

Yeosu (Korean: 여수; Korean pronunciation:; formerly romanized as Yŏsu) is a coastal city located in Jeonnam-Gwangju, South Korea. It has a population of 268,823.

In 1998, the old city of Yeosu, the city of Yeocheon, and Yeocheon County were merged to form the current city.

The city was once part of South Jeolla Province, but on July 1, 2026, that province was dissolved and merged with Gwangju into the provincial-level city of Jeonnam-Gwangju. Now, the city is directly managed under Jeonnam-Gwangju.
