The 1820 United Kingdom general election was held on 6 March 1820 to 14 April 1820, to elect members of the House of Commons, the lower house of Parliament. Triggered by the death of King George III, it produced the first parliament of the reign of his successor, King George IV. It was held shortly after the Radical War in Scotland and the Cato Street Conspiracy. In this atmosphere, the Tories under the Earl of Liverpool were able to win a substantial majority over the Whigs.

The sixth United Kingdom Parliament was dissolved on 29 February 1820. The new Parliament was summoned to meet on 21 April 1820, for a maximum seven-year term from that date. The maximum term could be and normally was curtailed, by the monarch dissolving the Parliament before its term expired.
