Nam I-heung (1576-1627) was a mid-Joseon military officer of Uiryeong, with courtesy name Saho, pen name Seongeun and posthumous title Chungjang. His father Nam Yu is said to have died at the naval battle of Noryang. After passing the military examination he served as royal guard officer, deputy commander, police chief, army commander of Chungcheong and Gyeongsang, and magistrate of Guseong and Anju. Impeached after the 1623 Restoration, he was spared through the defence of Field Marshal Jang Man.
In the 1624 rebellion of Yi Gwal he served under Jang Man, was made magistrate of Yeonan, named a first-class Jinmu merit subject and enfeoffed as Lord Uichun. He later became Army Commander of Pyeongan and magistrate of Yeongbyeon.
In the 1627 Later Jin invasion he held Anju until weapons ran out and the walls were about to fall, then lit the powder magazine and died with Kim Eon-su and others. He was posthumously made Chief State Councillor and Prince, and enshrined at Chungminsa in Anju. His tomb complex at Doi-ri, Daehoji-myeon, Dangjin, is South Chungcheong Monument No. 52 (designated 1984), beside his father's tomb, with the shrine Chungjangsa and the Namssi yangse chungsin memorial gate in front.
For helping put down the rebellion under Field Marshal Jang Man he was made a first-class Jinmu merit subject and enfeoffed as Lord Uichun.

The tomb complex at Daehoji-myeon, Dangjin, is South Chungcheong Monument No. 52. His family relics were designated an Important Folklore Material in 1970 and renamed "Relics of General Nam I-heung's Family" in 2004. His birth year is written differently in some sources, so check them.

He is introduced as the founder of the Chungjang-gong branch of the Uiryeong Nam.
