Óláfsdrápa sænska was a skaldic poem composed by Óttarr svarti in honour of the Swedish king Olof Skötkonung.
Óttarr spent some time with the Swedish king and worked eagerly for peace between Olof and the Norwegian king Olaf the Stout.
The remaining fragments of Óláfsdrápa sænska are of some value for our knowledge of the life of Olof Skötkonung as it contradicts Snorri Sturluson's depiction of Olof as a passive king. In Óláfsdrápa sænska Óttarr depicts Olof as having made glorious Viking expeditions in Eastern Europe.
