Frøylandsvatnet is a lake in Rogaland county, Norway. The 4.83-square-kilometre (1.86 sq mi) lake is located in the district of Jæren. It forms part of the municipal boundary line between Klepp and Time. The lake is quite shallow, with an average depth of 5.5 metres (18 ft).
The town of Bryne is located at the south end of the lake. The villages of Klepp stasjon, Orstad, and Kvernaland are all located around the northern end of the lake. The origin of the name is from the Norse god Frey.
The lake is located in an area with very intensive agriculture. Early in the 1980s the lake was identified as being one of the worst cases of eutrophication in Norway. Algal bloom was a widespread problem, and there were cases reported of poisonous algea causing cattle to die from drinking the water.
The release of substances containing nitrogen and phosphorus has since been reduced, but large collections of sediment in the shallow lake causes the problems to decline rather slowly.
