Hadselfjorden or Hadselfjord is a fjord in Vesterålen, Norway. The fjord separates the island of Hadseløya (on the north and west side of the fjord) from the islands of Austvågøya and Hinnøya island (on the south and east side of the fjord). In the northeast, the Hadselfjorden connects with Sortlandssund strait, which separates the islands of Langøya and Hinnøya.

A ferry passes between the villages of Melbu and Fiskebøl across the Hadselfjorden.
