Thetford was a constituency of the British House of Commons. It elected two Members of Parliament (MPs) by the bloc vote system of election. It was disenfranchised under the Representation of the People (Scotland) Act 1868, which had resulted in a net increase of seven seats in Scotland, offset by the disenfranchisement of seven English Boroughs.
Below are those MPs who held the seat from just prior to the Restoration onwards.
