Jinhan is a loose confederacy of chiefdoms that exists from around the 1st century BCE to the 4th century CE in the southern Korean peninsula, to the east of the Nakdong River valley, Gyeongsang Province.

Jinhan is one of the Samhan (or "Three Hans"), along with Byeonhan and Mahan.

Apparently descending from the Jin state of southern Korea, Jinhan is absorbed by the later Silla, one of the Three Kingdoms of Korea.
