2018–19 CSA Women's Provincial T20 Competition

The 2018–19 CSA Women's Provincial T20 Competition was the 7th edition of South Africa's provincial Twenty20 cricket tournament. It ran from October 2018 to February 2019, with 16 provincial teams taking part. North West won the tournament, claiming their first T20 title.

Competition format
The 16 teams were divided into three divisions: a top division named "Top 6", and two lower divisions, Pools A and B. Teams played each other team in their group once in a round-robin format, with matches played using a Twenty20 format. The winner of the Top 6 group was crowned Champions.

The tournament ran concurrently with the 2018–19 CSA Women's Provincial League, with matches played either the day before or day after the corresponding encounter between two teams in the one-day tournament. To maintain this link for the following season, promotion and relegation in the Provincial T20 Competition was determined by standings in the Provincial League.

The groups worked on a points system with positions being based on the total points. Points were awarded as follows:

Win: 4 points

Tie: 3 points

Loss: 0 points.

Abandoned/No Result: 2 points.

Bonus Point: 1 bonus point available per match.
