Pressmennan Lake is a lake in East Lothian in Scotland.
It is an artificial reservoir constructed in 1819. It lies in a gully in the Lammermuir Hills, above the village of Stenton in East Lothian. It is roughly 2 kilometres in length but less than 100 metres broad.
It is one of only a few bodies of water in Scotland known as lakes; the others include the Lake of Menteith, Lake of the Hirsel and Lake Louise (within the grounds of Skibo Castle). Only the Lake of Menteith is a natural body of water.
