Hudiksvall County, or Hudiksvalls län, was a county of the Swedish Empire, between 1645 and 1654. It was created by splitting the Norrland County into the Hudiksvall County and the Härnösand County, but just nine years later they were merged again as the Västernorrland County. The seat of residence for the Governor was in Hudiksvall.
