Parliamentary representation from Huntingdonshire

The historic county of Huntingdonshire, located in the modern-day East of England region, has been represented in the Parliament of the United Kingdom since the 13th century. This article provides the list of constituencies which have formed the parliamentary representation from Huntingdonshire.

In 1889 the area of the historic county formed the administrative county of Huntingdonshire. In 1965 the administrative county was merged with the Soke of Peterborough. Peterborough had been an administrative county which was part of the historic county of Northamptonshire. In 1974 Huntingdon and Peterborough was combined with the administrative county of Cambridgeshire and Isle of Ely, to form a new expanded non-metropolitan county of Cambridgeshire.

The first part of this article covers the constituencies wholly or predominantly within the area of the historic county of Huntingdonshire, both before and after the administrative changes of 1889, 1965 and 1974. The second part refers to constituencies mostly in another historic county, which included some territory from the historic county of Huntingdonshire. The summaries section only refers to the constituencies included in the first section of the constituency list. For more information on the constituencies currently covering the modern-day ceremonial county of Cambridgeshire, see List of parliamentary constituencies in Cambridgeshire.
