Kulivatnet is a lake in the municipality of Sirdal in Agder county, Norway. It sits just downhill from the border with Bjerkreim municipality in Rogaland county. The 2.16km2 lake is somewhat V-shaped and it has a small dam on the southeastern side to hold water for hydroelectric power generation. The water flows south through a series of dammed lakes before emptying into the river Sira at Tonstad, about away.
