Øvre Tysdalsvatnet is a lake in Hjelmeland Municipality in Rogaland county, Norway. The 9-square-kilometre (3.5 sq mi) lake lies on the east side of the village of Årdal. The 12-kilometre (7.5 mi) long lake is only about 800 metres (0.5 mi) wide and it has a fairly steep shoreline, which results in very little habitation around the lake.

The name "Øvre" Tysdalsvatnet means "upper" Tysdalsvatnet to distinguish it from the lake Tysdalsvatnet located about 5 kilometres (3.1 mi) to the southwest.
