The 2021 SPAR Challenge is the sixth edition of the netball Challenge Tournament organised by Netball South Africa. The series is being contested by three South African teams (the senior national team, the national "B" team known as the President's XII, and the under-21 team known as the Baby Proteas), the Ugandan national team, and the Namibian national team. The tournament was originally scheduled to occur in January 2021, though was postponed to March due to a resurgence of COVID-19 cases in South Africa. The tournament is sponsored by SPAR, is broadcast by SuperSport and will be held at the Cape Town International Convention Centre.
