The Incheon-class frigates (Hangul: 인천급 호위함), also known as Future Frigate eXperimental or FFX during development, are coastal defense frigates of the Republic of Korea Navy. The lead ship was launched on April 29, 2011. The Incheon-class frigates will replace the aging fleet of Pohang-class corvettes and Ulsan-class frigates, and take over multi-role operations such as coast patrol, anti-submarine warfare and transport support. Later batches are planned to be specialized on anti-air and anti-submarine warfare.

A variant of the Incheon-class is being built by South Korean defense manufacturer Hyundai Heavy Industries to the Philippines' Department of National Defense for their requirement of two new frigates.
