Hunneberg, Mountain nature reserve in Vänersborg, Sweden.

Hunneberg is a flat-topped table mountain just east of Vänersborg and Trollhättan, rising about 90 metres above the surrounding farmland. Its roughly 70 square kilometres of poor, level ground are covered in bogs and forest, and the plateau ends in vertical cliff faces. Next to it lies the smaller Halleberg, also a table mountain.

Hunneberg has been a royal hunting ground since Magnus Eriksson's national law of 1351, though the right was first exercised in 1885 with the first Kungajakt. Alum shale was quarried along the foot of the mountain from the second half of the 18th century until the 1950s, and lime was burned from the shale for agriculture. Remains of the kilns and quarry caves survive near Västra Tunhem.

Hunneberg has been a royal hunting ground since Magnus Eriksson's law of 1351, though the right was first exercised in 1885 with the first royal hunt. At Bergagården, the Kungajaktmuseet Älgens Berg museum documents this tradition and the moose hunt.

The trails can be accessed from several entry points, including Flo on the eastern side and Vargön or Tunhem from other directions. Visitors should wear proper hiking boots and bring waterproof layers, as weather changes quickly in this exposed terrain.

Hunneberg holds one of Sweden's two GSSP markers, the international reference point defining a geological stage boundary. The site lies on the mountain's plateau, near the Kungajaktmuseet at Bergagården, where the royal hunt tradition is documented.
