The 1987 United Kingdom general election was held on Thursday 11 June 1987, to elect 650 members to the House of Commons. The election was the third consecutive general election victory for the Conservative Party, who won a majority of 102 seats and second landslide under the leadership of Margaret Thatcher, who became the first Prime Minister since the Earl of Liverpool in 1820 to lead a party into three successive electoral victories.

The Conservative and Unionist Party, commonly the Conservative Party and colloquially known as the Tories, is one of the two main political parties in the United Kingdom, along with the Labour Party. It is the current governing party, having won the 2019 general election, and has been the primary governing party in the United Kingdom since 2010. The party sits on the right-wing to centre-right of the political spectrum. It encompasses various ideological factions including one-nation conservatives, Thatcherites, and traditionalist conservatives. The party holds the annual Conservative Party Conference, at which senior Conservative figures promote party policy.
