The 1959 United Kingdom general election was held on Thursday, 8 October 1959. It marked a third consecutive victory for the ruling Conservative Party, now led by Prime Minister Harold Macmillan. For the second time in a row, the Conservatives increased their overall majority in Parliament, this time to a landslide majority of 100 seats, having gained 20 seats for a return of 365. The Labour Party, led by Hugh Gaitskell, lost 19 seats and returned 258. The Liberal Party, led by Jo Grimond, again returned only six MPs to the House of Commons, but managed to increase its overall share of the vote to 5.9%, compared to just 2.7% four years earlier.

The Conservatives won the largest number of votes in Scotland, but narrowly failed to win the most seats in that country. They have not made either achievement ever since. Both Jeremy Thorpe, a future Liberal leader, and Margaret Thatcher, a future Conservative leader and eventually Prime Minister, first entered the House of Commons after this election.
