Scottish UK Parliamentary Constituencies (or Westminster Constituencies) define the electoral areas of Scotland used to return members to the Parliament of the United Kingdom in UK general elections. They are different from the Scottish Parliamentary Constituencies, which are used to return members to the Scottish Parliament. There are currently 59 Westminster constituencies in total, each electing one Member of Parliament. The Boundary Commission for Scotland is responsible for recommendations on the definition of constituency boundaries, however, the definitive dataset is delineated by Ordnance Survey for inclusion in their BoundaryLine product.
