Tayvallich, pronounced "Tay-vee-al-ich" (Scottish Gaelic: Taigh a' Bhealaich Scottish Gaelic pronunciation: [t̪ʰɤj ə ˈvjal̪ˠɪç]), is a small village in the Knapdale area of Argyll and Bute, in Scotland. The village name has its origins in Gaelic, and means the "house of the pass". The village is built around a sheltered harbour on Loch Sween. It has a primary school, small caravan park, pub and village store. The local economy is based on tourism and fishing. There is also a local bus service that takes the older children to nearby Lochgilphead where the nearest high school is situated. Tayvallich has become a popular sailing centre. During the Summer months a fast ferry (RIB) operates from Tayvallich to Craighouse, Isle of Jura six days a week.
Tayvallich is split into two areas; Carsaig and Tayvallich. Loch Sween cuts NE into the Knapdale peninsula and the western shore of the loch forms a smaller peninsula. Towards the north end of this peninsula an isthmus is formed about a kilometre wide and the East side has an almost landlocked bay which is where Tayvallich is located and the West side of the isthmus is Carsaig Bay. A road now links Tayvallich and Carsaig.
