Loch Fyne (Scottish Gaelic: Loch Fìne, pronounced [ɫ̪ɔx fiːnə]) is a sea loch on the west coast of Argyll and Bute, Scotland. It extends 65 kilometres (40 miles) inland from the Sound of Bute, making it the longest of the sea lochs. It is connected to the Sound of Jura by the Crinan Canal.
Loch Fyne is famous for its oyster fishery, and as a consequence the loch has given its name to the locally owned Loch Fyne Oysters, and the associated Loch Fyne Restaurants.
Loch Fyne is a popular area for sport diving and fishing. It is also a popular tourist destination with attractions such as Inveraray Castle and the nearby ruins of Castle MacEwan and Castle Lachlan.
