Dorset was a county constituency covering Dorset in southern England, which elected two Members of Parliament (MPs), traditionally known as knights of the shire, to the House of Commons of England from 1290 until 1707, to the House of Commons of Great Britain from 1707 to 1800, and to the House of Commons of the United Kingdom until 1832.

The Great Reform Act increased its representation to three MPs with effect from the 1832 general election, and under the Redistribution of Seats Act 1885 the constituency was abolished for the 1885 election, and replaced by four single-member divisions: North Dorset, South Dorset, East Dorset and West Dorset.

When elections were contested, the bloc vote system was used, but contests were rare. Even after the 1832 Reforms, only three of the nineteen elections before 1885 were contested; in the others, the nominated candidates were returned without a vote.
