Portavadie (Scottish Gaelic: Port a' Mhadaidh) is a village on the shores of Loch Fyne on the coast of the Cowal Peninsula, in Argyll and Bute, West of Scotland.

[1] The Portavadie complex was built in 1975[2] by the then Scottish Office for the purpose of constructing concrete platforms for extraction of oil from the North Sea.

Despite suggestions to turn the complex into a holiday village, it lay redundant until in the mid-1980s the enclosed port was used by a local fish farm company.

[3][4][5] In late 2009 the marina was used for the first time to tie up yachts for the Scottish series by the Clyde Cruising Club, won by Nigel Biggs; England; J109-IRC.

The first phase of the complex consisted of five-star luxury apartments, with private sauna facilities and four-star cottages, alongside a restaurant, conference suites and a retail space.
