Skoglar Toste or Skoglar Tosti (there are several variations) is a legendary 10th century chieftain from the Swedish province of West Gothland. Snorri Sturlusson recounts in Heimskringla that he was a great Viking who often waged war and that is why he was called "Skagul's Tosti". Skagul was a Valkyrie.
Toste is mentioned in several sagas, most notable in Heimskringla. According to Snorri Sturluson, he was the father of Sigrid the Haughty. For some time he gave refuge to Harald Grenske, who later came back to woo Sigrid, only to be killed by her for his persistence. According to the sagas, Skoglar Toste was also the father of Ulf Tostesson, father of Ragnvald Ulfsson and grandfather of Stenkil who became the King of Sweden in 1060.
