Clitheroe was a parliamentary constituency in Lancashire. The town of Clitheroe was first enfranchised as a parliamentary borough in 1559, returning two Members of Parliament (MPs) to the House of Commons of England until 1707, then to the House of Commons of Great Britain until 1800, and finally to the House of Commons of the Parliament of the United Kingdom until 1832. The borough's representation was reduced to one MP by the Reform Act 1832.
