Ulf of Borresta (Old Norse: Ulfr í Báristöðum, modern Swedish: Ulf i Borresta) was a runemaster in the eleventh century Uppland, Sweden, and a successful Viking who returned from England three times with a share of the Danegeld. He is named after his estate which in modern Swedish is called Borresta or Bårresta (Old Norse: Báristaðir[1] or Bárastaðiʀ[2]).
