Ytraberget is a peninsula in Hafrsfjord, which lies to the north of the coastal landscape Jæren. The peninsula is part of the municipality Sola in Norway and is known for the battle in 872, when Harald Fairhair (Harald Hårfagre ) united Norway into one kingdom. Snorri Sturluson relates in his chronicle Heimskringla that Harald has recovered from a fortress on Ytraberget the battle.

In fact there are still remains of a fortification from the time of the migration. King Olav V in 1972 unveiled a memorial stone on the Ytraberg at the 1100 anniversary of the emergence of Norway.
