Laguna Blanca is a salt lake in an endorheic basin, in the Sur Lípez Province of the Potosí Department, Bolivia.

The lake is at an elevation of 4,350 metres (14,270 ft) on the Altiplano.

The characteristic white colour of the water, that gave the lake its name, is caused by the high amount of minerals suspended in it.

Both are within the Eduardo Avaroa Andean Fauna National Reserve.
