The 1983 United Kingdom general election in Wales took place on 9 June 1983 for all 38 Welsh seats to the House of Commons. The Labour Party again won a majority of Welsh MPs, but the party's vote share declined by 9.4% and they lost three seats. In this election popular vote and percentage gap produced between Labour and Conservative parties will be the smallest one up until 2019 UK general election. The governing Conservatives made a net gain of two seats, with the SDP–Liberal Alliance gaining one.
