# Parliamentary representation from Cambridgeshire

The historic county of Cambridgeshire, located in the modern-day East of England region, has been represented in Parliament since the 13th century. This article provides the list of constituencies which have formed the parliamentary representation from Cambridgeshire.
In 1889 the historic county was divided between the administrative counties of Cambridgeshire and Isle of Ely. The two administrative counties merged in 1965 to form Cambridgeshire and Isle of Ely. In 1974 Cambridgeshire and Isle of Ely was merged with Huntingdon and Peterborough to form a new expanded non-metropolitan county of Cambridgeshire. Huntingdonshire was a historic and administrative county in its own right, whereas the Soke of Peterborough had been an administrative county which was part of the historic county of Northamptonshire.
