Lake Guinas is the larger of only two permanent natural lakes in Namibia. It is a sinkhole lake, created by a collapsing karst cave,^[1] located thirty-eight kilometres west of Tsumeb, near the D3043 road.

Lake Guinas is home to Tilapia guinasana, a critically endangered species of cichlid fish, endemic to this lake, but at some stage introduced to Guinas' sister lake, Lake Otjikoto, as well as into a few farm dams nearby.^[2] The claim that lake Guinas is indeed connected to lake Otjikoto by caves is frequently made but not proven as yet.^[1]

The lake is situated on private farmland but can be visited with the permission of the owner.
