The Chungnam-class frigate is a class of frigates of the Republic of Korea Navy (ROKN). The Chungnam class is based on the preceding Daegu class. Which in turn is based on the Incheon class, and has otherwise been referred to as the Incheon-class batch III, FFX-III, or FFG-III.

Confusingly, the FFX Batch III is sometimes called the Ulsan class. The Ulsan class, were the predecessors to the FFX program, preceding the Incheon-class (FFX-I class). Ulsan is also the name of FFX Batch IV.
