Western Cape is a Geographical Unit within the Wine of Origin classification system of South African wine. Corresponding to the province of Western Cape it includes most of the vineyards in South Africa.

South African wine has a history dating back to 1659 with the first bottle being produced in Cape Town by its founder and governor Jan van Riebeeck. Access to international markets led to new investment in the South African wine market. Production is concentrated around Cape Town and almost exclusively located within the Western Cape province, with major vineyard and production centres at Constantia, Paarl, Stellenbosch and Worcester.
