2019–20 Senior Women's One Day Trophy

It was scheduled to be played from 18 February to 20 March 2020 in a round-robin and knockout format.

[1] There was therefore no overall winner, although three teams were promoted from the Plate Group.

Teams in the Plate Group competed for promotion to the Elite Group, with three teams achieving this for the following season, whilst teams in the Elite Group competed to progress to the knockout stage quarter-finals, which were cancelled due to the COVID-19 pandemic.

[1][2] The groups worked on a points system with positions within the group based on the total points of each team.

If points in the final table were equal, teams were separated first by most wins, then by head-to-head record, and then Net Run Rate.
