The 2019–20 CSA 3-Day Provincial Cup was a first-class cricket competition that took place in South Africa from October 2019 to April 2020.
KwaZulu-Natal finished top of group B, with Easterns named joint-winners despite not topping their group, but played one match fewer than other teams, with their victory coming via an average points calculation.
[7][8] Unlike its counterpart, the CSA Franchise 4-Day Cup, the matches were three days in length instead of four.
The tournament was played in parallel with the 2019–20 CSA Provincial One-Day Challenge, a List A competition which featured the same teams.
[10] In January 2020, Andrea Agathangelou and Yaseen Valli made an opening partnership of 485 runs for Easterns against Boland, breaking the previous record in a first-class match in South Africa of 424 runs set in the 1926–27 season.
