"The Bonnie Banks o' Loch Lomond", or "Loch Lomond" for short, is a Scottish song. The song prominently features Loch Lomond, the largest Scottish loch, located between the council areas of West Dunbartonshire, Stirling and Argyll and Bute. In Scots, "bonnie" means "attractive", "beloved", or "dear".

Loch Lomond is a freshwater Scottish loch which crosses the Highland Boundary Fault, often considered the boundary between the lowlands of Central Scotland and the Highlands. Traditionally forming part of the boundary between the counties of Stirlingshire and Dunbartonshire, Loch Lomond is split between the council areas of Stirling, Argyll and Bute and West Dunbartonshire. Its southern shores are about 23 kilometres (14 mi) northwest of the centre of Glasgow, Scotland's largest city. The Loch forms part of the Loch Lomond and The Trossachs National Park which was established in 2002.
