Karmsundsposten was a Norwegian newspaper, published in Haugesund in Rogaland county, Norway.

Karmsundsposten was started in 1861, as the first newspaper in the middle-sized city. It took its name from the Karmsundet strait between Haugesund and Karmøy. In 1915 it was absorbed by the Labour Party newspaper Haugesunds Folkeblad.[1]
