The Portsmouth South by-election was held on 14 June 1984, following the death of Bonner Pink, the Conservative MP for Portsmouth South.

Portsmouth South was considered a safe seat for the Conservatives. Pink had held the constituency since the 1966 general election, while the party had held the seat since its creation in 1918. At the 1983 general election, Pink had taken just over half the votes cast.^[1]
