Scotland became part of the Kingdom of Great Britain under the Acts of Union 1707 from 1 May 1707. It became part of the United Kingdom from 1 January 1801.

Under the terms of the Act of Union 1707, Scotland was entitled to 45 members of the House of Commons of the Westminster Parliament.

A Scottish law passed before the Union defined the constituencies for elections to the Parliament of Great Britain. There was a special provision for the selection of Members of Parliament for the 1st Parliament of Great Britain.

In 1707, members of the former Parliament of Scotland were co-opted to serve in the 1st Parliament of Great Britain. See Scottish representatives to the 1st Parliament of Great Britain, for details.

Key to categories: BC - Burgh constituencies, CC - County constituencies, UC - University constituencies, Total C - Total constituencies, BMP - Burgh Members of Parliament, CMP - County Members of Parliament, UMP - University Members of Parliament.

Notes:

1. Compass point and similar names for Divisions of counties often officially precede the name of the county (Central Aberdeenshire). This list uses the Burgh equivalent form (Aberdeenshire Central), for the first area included in the constituency name. This does not apply to areas where the county name is e.g. East Lothian, or the town name is e.g. East Kilbride.
2. The County etc. column includes the historic/administrative county or local government region in which a constituency was included when it was created. Local government boundaries used for a redistribution were sometimes obsolete by the time the new constituencies were first used. Official names of counties did sometimes change (e.g. Edinburghshire and Midlothian). Constituencies created in 2005 have no local area mentioned. A constituency covering more than one such area has the predominant area (or for Districts of Burghs the county of the first named Burgh) recorded.

A cell marked → (with a different colour background to the preceding cell) indicates that the previous MP continued to sit under a new party name.
