Ulf the Brave (Úlfr inn óargi) was a Norwegian hersir who lived in Namdalen in the eighth century CE. He was the father of Hallbjörn Half-Troll and Hallbera Ulfsdóttir, who was the mother of Kveldúlfr Bjálfason. Thus Ulf the Brave was the ancestor of the clan of Egill Skallagrimsson. He is briefly mentioned in Egils Saga.
According to Skáldatal B (Codex Upsaliensis) Ulf was a skald. In one single night he composed a drápa praising his own heroic deeds. He died before dawn.
The drápa is not preserved.
