The Sin Hung-class patrol boat is a class of patrol boats in service with the Korean People's Navy.

The class is based on the same hull as the Sin Hung-class hydrofoil torpedo boat, and Sin Hung-class torpedo boat.

[1] Construction of the Sin Hung class was first noticed in early 1984, when six Sin Hung hulls were seen being built without torpedo tubes or sponsons.

A total of eight were seen to be built, all at the Nampo Shipyard.

Two of these were sold to Nicaragua in late May of the same year.
