The 1999 Western Cape provincial election was held on 2 June 1999, concurrently with the 1999 South African general election, to elect the 2nd Western Cape Provincial Parliament.
The election resulted in no overall control of the Provincial Parliament, but brought the African National Congress to a plurality of seats at the expense of the New National Party, as well as gains for the Democratic Party. Despite the result, the NNP formed a coalition with the DP, and incumbent Gerald Morkel remained premier.
