Linlithgow is a constituency of the Scottish Parliament (Holyrood). It elects one Member of the Scottish Parliament (MSP) by the plurality (first past the post) method of election. Also, however, it is one of nine constituencies in the Lothians electoral region, which elects seven additional members, in addition to nine constituency MSPs, to produce a form of proportional representation for the region as a whole.

The Linlithgow constituency was created at the same time as the Scottish Parliament, in 1999, with the name and boundaries of an existing Westminster constituency. In 2005, however, Scottish Westminster (House of Commons) constituencies were mostly replaced with new constituencies.
The Holyrood constituency is one of two covering the West Lothian council area, the other being Livingston, east and south of the Linlithgow constituency.
