The Straume Nature Reserve (Norwegian: Straume naturreservat) is located in Bø Municipality in Nordland county, Norway.

[1] The nature reserve lies south of the village of Straume on the west side of the island of Langøya.

It includes two lakes—Førevatnet and Saltvatnet—and a shallow inlet called Skjørisen.

[2] The area is protected to preserve the central parts of an important wetland area with natural vegetation and wildlife, and especially a rich and specialized bird population.

[1] Norwegian County Road 820 passes between the two halves of the nature reserve.
