This article provides a list of constituencies constituting the Parliamentary representation from Buckinghamshire.
In 1974 a new non-metropolitan county of Buckinghamshire lost the Eton and Slough areas to Berkshire, while the part of Colnbrook formerly included in the county also became part of Berkshire in 1995.
The first part of this article covers the constituencies wholly or predominantly within the area of the historic county of Buckinghamshire, both before and after the administrative changes of 1889, 1974 and 1995.
Article names are followed by (UK Parliament constituency).
The constituencies which existed in 1707 were those previously represented in the Parliament of England.
