2023 Ontario Scotties Tournament of Hearts

The 2023 Ontario Scotties Tournament of Hearts, the provincial women's curling championship for Southern Ontario, was held from January 23 to 29 at The Plex in Port Elgin, Ontario. The winning Rachel Homan rink represented Ontario at the 2023 Scotties Tournament of Hearts, Canada's national women's curling championship in Kamloops, British Columbia where they made the Championship round losing to Nova Scotia 7–6 in an extra end.

The event was held in conjunction with the 2023 Ontario Tankard, the provincial men's curling championship. Both events are held together in non-Olympic years.

Qualification process
Twelve teams qualified for the 2023 Ontario Scotties. As defending champions, Team Rachel Homan earned the first qualification spot (due to COVID-19 the 2022 Ontario Hearts were postponed until after the national Tournament of Hearts). One team qualified via their results in the "Grand Slam" series events (2022 PointsBet Invitational, 2022 National, 2022 Tour Challenge, 2022 Masters). Two teams qualified via their results in the Trillium Tour '1000' series events (Stu Sells Toronto Tankard, Stroud Sleeman Cash Spiel, North Grenville Curling Club Women's Fall Classic, Stu Sells Brantford Nissan Classic). Three teams qualified via their results in the Trillium Tour '500' series events (Gord Carroll Curling Classic, KW Fall Classic, CurlON Women's Open, Home Again Women's Classic, plus the aforementioned 1000 events). One team (restricted to curlers under the age of 25) qualified via their results in the aforementioned Trillium Tour events, plus the CurlON 250 Event #1.
