Lochranza (Scottish Gaelic: Loch Raonasa) is a village located on the Isle of Arran in the Firth of Clyde, Scotland. The population, somewhat in decline, is around 200 people.
It is the most northernly sited of Arran's villages and is located in the northwestern corner of the island. The village is set on the shore of Loch Ranza, a small sea loch. Ferries run from here to Claonaig on the mainland. The village is flanked to the northeast by the landmark hill Torr Meadhonach.
Formerly a herring fishing port, the village economy is now geared more towards tourism after the reopening of the pier in 2003. Lochranza Castle is a fine ruin of a 16th-century L-plan castle, across the road from the Lochranza youth hostel.
Lochranza is the site of the Arran Distillery, built in 1995 and producing the Arran Single Malt. The distillery is one of the major industries of the island. The bar of the Lochranza Hotel, to the north of the distillery, has one of the largest collections of Scotch whisky available by the measure in the country: over 350 different Scotch whiskies are available.
