Wonsan-class minelayer (Korean: 원산급 기뢰부설함; Hanja: 元山級機雷敷設艦) or MLS-I (Mine Laying Ship-I) is a one-ship class of minelayers currently in service on the Republic of Korea Navy.

The Republic of Korea Navy planned to commission three Wonsan class mine layers. However, due to budget problems, only one was commissioned.
