The Ulaid (Old Irish, ) or Ulaidh (modern Irish, ) were a people of early Ireland who gave their name to the modern province of Ulster (modern Irish: Cúige Uladh, meaning "fifth-part of the Ulaidh"). The English word Ulster derives from Irish Ulaidh and Old Norse staðr (meaning "place, territory").
In medieval texts they are also referred to as the Clanna Rudraige (modern spelling: Clanna Rudhraighe, anglicization: Clanna Rury) meaning "descendants of Rudraige" – whence the modern Irish term Rúraíocht (the Ulster Cycle of Irish mythology).
