Juklevatnet is a lake in the municipalities of Hemsedal (in Buskerud county) and Lærdal (in Vestland county), Norway. It is located 21 kilometres (13 mi) east of Borgund in Lærdal, just to the south of the mountain Høgeloft in the Filefjell range. The 3.07-square-kilometre (1.19 sq mi) lake sits at an elevation of 1,286 metres (4,219 ft) above sea level. It is located 5 kilometres (3.1 mi) northeast of the lake Eldrevatnet and 10 kilometres (6.2 mi) northeast of the lake Øljusjøen.

The lake is regulated by a hydroelectric dam which is part of a nearby power station. The water flows into the lake Vesle Juklevatnet, then the river Jukleåni, and then into the lake Eldrevatnet.
