Lairg (gael An Luirg) is a village in Sutherland in the northern Highlands in Scotland. It has about 900 inhabitants. Lairg is located at the southeastern end of Loch Shin, making it one of the few settlements of this size in the northern Highlands that are not on the coast. Its importance for the north, Lairg owes to the railway connection during the 19th century. Otherwise, the place is still accessible via two single-lane roads. In addition, Lairg is an important market for sheep. It hosts some of Europe's largest auctions. An archeological trail on Ord Hill is signposted at Lairg. South of the village are the Falls of Shin, where salmon can be seen from a visitor's platform while overcoming the rapids.
