The Battle of Stiklestad (, Old Norse: Stiklarstaðir) in 1030 is one of the most famous battles in the history of Norway. In this battle, King Olaf II of Norway (Old Norse: Óláfr Haraldsson) was killed. He was later canonized. His younger half-brother, Harald Sigurdsson, was also present at the battle and would in 1047 go on to become King of Norway, only to die in a failed invasion of England in the Battle of Stamford Bridge in 1066. Harald was only fifteen when the battle of Stiklestad took place.
