Tyssestrengene are waterfalls east of the village of Tyssedal in Ullensvang Municipality, in Vestland county, Norway.
The waterfalls are fed by the Tysso River before flowing down into the lake Ringedalsvatnet.
The Trolltunga cliff is located near the waterfalls.
The total drop is 646 metres (2,119 ft), while the tallest single drop is 312 metres (1,024 ft).
Following their incorporation in the Norwegian Hydroelectric Power Authority, their water flow is diminished to such a point that only after heavy snow melts is there any flow of substance.
