Loch Loskin is a freshwater loch in Ardnadam, Argyll and Bute, Scotland. The outflow from the loch is the Milton Burn, which winds its way through Dunoon to the Firth of Clyde. The A885 from Sandbank, known as the "High Road" locally, passes the loch.

There are several beautiful sylvan walks in the neighbourhood. One of these is that which leads by the little freshwater lake, Lochenloskin, to Dunoon. Lochenloskin is the favourite haunt of the waterlily, where absolutely acres of the surface are covered with the snow-white blossoms of the plant.
