Markkleeberger See (in English: Lake Markkleeberg) is an artificial lake in Saxony, Germany, next to Markkleeberg, a suburb on the south side of Leipzig. At an elevation of 112.5 m, its surface area is 2.52 km2. It is a former open-pit coal mine, flooded in 1999 with groundwater and developed in 2006 as a tourist area. On its southeastern shore is Germany's only pump-powered artificial whitewater slalom course, the Kanupark Markkleeberg.

An assortment of mining equipment once in use in the area has been collected into an open-air museum.
