The Currie Cup tournament is South Africa's premier domestic rugby union competition, played each winter and spring (June to October), featuring teams representing either entire provinces or substantial regions within provinces. Although it is the premier domestic competition, South African teams also compete in the international Pro14 competitions. Steeped in history and tradition, the Currie Cup dates back to 1891. The tournament is regarded as the cornerstone of South Africa's rugby heritage, and the coveted gold trophy remains the most prestigious prize in South African domestic rugby.
