Donghu (literally: "Eastern Foreigners" or "Eastern barbarians") is the name of a Mongolic nomadic tribal confederation that is first recorded from the 7th century BCE and is destroyed by the Xiongnu in 150 BCE.

Donghu is later divided into the Wuhuan and Xianbei Confederations, from which the Mongols are derived.

Hence, in modern linguistic terminology, they are classified as a proto-Mongolic nomadic ethnic group.
