Yeavering is a very small hamlet in the northeast corner of the civil parish of Kirknewton in the English county of Northumberland. It is located on the River Glen at the northern edge of the Cheviot Hills. It is noteworthy as the site of a large Anglo-Saxon settlement that archaeologists have interpreted as being one of the seats of royal power held by the kings of Bernicia in the 7th century AD.
