# Kilmarnock and Loudoun (UK Parliament constituency)

Kilmarnock and Loudoun is a county constituency of the House of Commons of the Parliament of the United Kingdom. It elects one Member of Parliament (MP), using the first-past-the-post voting system. It has been represented since 2024 by Lillian Jones of Scottish Labour.

## Boundaries

The constituency consists of the northern and central areas of East Ayrshire and contains the town of Kilmarnock and the Irvine Valley. It does not share the same borders as the former Scottish Parliament constituency of the same name.
There was a Kilmarnock and Loudoun local government district covering a similar area, from 1975 to 1996. At the 1983 general election, this district was coterminous with the constituency boundaries
Under the Fifth Review of UK Parliament constituencies, the constituency was expanded to include part of the abolished Carrick, Cumnock and Doon Valley constituency; the boundaries were defined in accordance with the ward structure in place on 30 November 2004. Under the 2023 review of Westminster constituencies, which came into effect for the 2024 general election, the boundaries were unchanged.
Further to reviews of local government ward boundaries which came into effect in 2007 and 2017, but did not affect the parliamentary boundaries, the contents of the constituency are now defined as comprising the following electoral wards of the East Ayrshire council area:
* Annick, Ballochmyle, Irvine Valley, Kilmarnock East and Hurlford, Kilmarnock North, Kilmarnock South, Kilmarnock West and Crosshouse, and a very small part of Cumnock and New Cumnock.
The main towns and villages are:
* Newmilns and Greenholm
* Catrine *
* Auchinleck *
* Darvel
* Galston
* Hurlford
* Kilmarnock
* Kilmaurs
* Logan *
* Lugar *
* Mauchline *
* Muirkirk *
* Ochiltree*
* Sorn *
* Stewarton
* Dunlop
Those towns marked * were not part of the original Kilmarnock and Loudoun, but were absorbed from the disbanded Carrick, Cumnock and Doon Valley.
