Scandinavian York or Viking York is a term used by historians for what is now Yorkshire during the period of Scandinavian domination from late 9th century until it was annexed and integrated into England after the Norman Conquest; in particular, it is used to refer to York, the city controlled by these kings and earls. The Kingdom of Jórvíc was closely associated with the much longer-lived Kingdom of Dublin throughout this period.

Yorkshire is an area of Northern England which was historically a county. Despite no longer being used for administration, Yorkshire retains a strong regional identity. The county was named after its original county town, the city of York.
