The Votadini, also known as the Uotadini, Wotādīni, Votādīni, or Otadini were a Brittonic people of the Iron Age in Great Britain. Their territory was in what is now south-east Scotland and north-east England, extending from the Firth of Forth and around modern Stirling to the River Tyne, including at its peak what are now the Falkirk, Lothian and Borders regions and Northumberland. This area was briefly part of the Roman province of Britannia. The earliest known capital of the Votadini appears to have been the Traprain Law hill fort in East Lothian, until that was abandoned in the early 5th century. They afterwards moved to Din Eidyn (Edinburgh).
