Liskeard was a parliamentary borough in Cornwall, which elected two Members of Parliament (MPs) to the House of Commons from 1295 until 1832, and then one member from 1832 until 1885. The constituency was abolished by the Redistribution of Seats Act 1885.

The parliamentary borough was based upon the community of Liskeard in the south-eastern part of Cornwall.

Sedgwick estimated the electorate at 30 in 1740. Namier and Brooke considered it was about 50 in the 1754–1790 period. The right of election before 1832 was in the freemen of the borough. This constituency was under the patronage of the Eliot family, which acquired the predominant interest by 1722.

There were no contested elections between at least 1715 and 1802. In the early 19th century the Whigs attempted to expand the electorate to include householders. During the 1802 general election, 48 householders claimed the right to vote but their ballots were rejected by the Mayor (see the note to the 1802 election result below). The Eliot family continued to control the borough in the Tory interest, for another thirty years.

The Reform Act 1832 augmented the freemen voters (who retained their ancient right votes), with the beneficiaries of a new householder franchise. The number of voters registered in 1832 was 218. The political effect of the change was that a Whig was elected unopposed to the one remaining seat in 1832, whereas the two Tory candidates had been elected unopposed at the previous seven general elections. Only Whig or Liberal candidates were returned from 1832 until the constituency was abolished.

The Reform Act 1867 preserved the borough constituency but slightly expanded the electorate (from 434 in 1865 to 881 in 1868). Liskeard was one of the smallest boroughs to retain individual representation in the 1868–1885 period. However the constituency was finally abolished by the Redistribution of Seats Act 1885, when the borough became part of the Bodmin or South East division of Cornwall.

Note on sources: The information for the election results given below is taken from Sedgwick 1715–1754, Namier and Brooke 1754–1790 and Stooks Smith 1790–1832. From 1832 the principal source was Craig, with additional or different information from Stooks Smith included. Candidates classified by Craig as Liberal before 1859, are labeled as Whig or Radical (following Stooks Smith) or Liberal if their exact allegiance is uncertain. Similarly candidates classified by Craig as Conservative but by Stooks Smith as Tory are listed below as Tory.

Note on percentage change calculations: Where there was only one candidate of a party in successive elections, for the same number of seats, change is calculated on the party percentage vote. Where there was more than one candidate for a party, in one or both successive contested elections for the same number of seats, then change is calculated on the individual candidates percentage vote.

Note on party allegiance of candidates: A party label is only used when the source used quotes one. Other candidates are labelled Non Partisan, but may have associated themselves with a tendency or faction in Parliament.
