Loch Earn (
Scottish Gaelic,
Loch Eire/Loch Éireann) is a freshwater
loch in the central
highlands of
Scotland, in the districts of
Perth and Kinross and
Stirling. The name is thought to mean "Loch of Ireland", and it has been suggested that this might derive from the time when the
Gaels were expanding their kingdom of
Dál Riata eastwards into
Pictland. It can be located on Satnav from postcodes including PH6 2NL.
