Stakkastadvatnet is a lake on the border of Rogaland and Hordaland counties in Norway. The lake mostly lies in Rogaland along the municipal borders of Haugesund and Tysvær. A very small portion of the northern part of the lake crosses over into the municipality of Sveio in Hordaland county. The lake lies about northeast of the town of Haugesund. The lake has a small dam on the northwestern edge of the lake. The natural outlet of the lake flows through the dam and into the nearby lake Vigdarvatnet, located to the north.
