Haga dolmen (Swedish: Hagadösen) is a megalithic tomb from the Neolithic, located in Stala parish about 1 km east of Tegneby church on Orust in Bohuslän, Sweden.
The dolmen consists of four raised slabs and a roof slab and has both a threshold stone at the entrance and a paving stone. It is surrounded by a small mound of earth and very inconspicuous curbs. It was probably built around 3400 BCE. and is one of the largest of its kind on the West Coast of Sweden. The dolmen was excavated in 1915, and pearls of amber, a stone axe, a flint knife and a piece of slate jewellery were found. These finds from the Senneolithic are from a later period than when the dolmen was made.
