Unified Silla (668 CE – 935 CE) or Later Silla is the name often applied to the Korean kingdom of Silla, one of the Three Kingdoms of Korea, when it conquers Baekje in 660 and Goguryeo in 668, unifying the southern portion of the Korean peninsula.

Its last king, ruling over a state in name only, submits to the emerging Goryeo in 935, bringing the dynasty to an end.
