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.
Loch Loskin is stocked with brown trout by Dunoon and District Angling Club.
The Loch Loskin strathspey was composed by Roderick Campbell.
