The 2016 Under-20 Provincial Championship was the 2016 edition of the Under-20 Provincial Championship, an annual national Under-20 rugby union competition held in South Africa. The competition was contested from 27 May to 7 October 2016. This season was the first season of a new Under-20 competition. Previously, all South African provincial unions competed in both an Under-21 and an Under-19 competition each season. That format was retained for the seven leading provincial unions at youth level, but the competition for the remaining eight provincial unions was changed to an Under-20 competition from 2016 onwards. The tournament was won by Griffons U20; they beat Boland U20 22–16 in the final played on 7 October 2016.
