2023 Centennial Cup

The 2023 Centennial Cup was the Canadian Junior Hockey League (CJHL) championship for the 2022–23 season and the 51st Canadian junior A ice hockey national championship, played at Stride Place in Portage la Prairie, Manitoba from May 11 to 21, 2023. For the second straight season, all nine CJHL league champions and the host team (Portage Terriers) participated in the tournament.

The Portage Terriers and city of Portage la Prairie were to be the host for the 2020 Centennial Cup, but were renamed as the 2023 host when the 2020 tournament was cancelled at the onset of the COVID-19 pandemic. Portage la Prairie was also host to the 2015 championship (then known as the RBC Cup), which was won by the Terriers. Tim Hortons, the title sponsor of the national junior 'A' championship, withdrew its sponsorship for the 2023 season in response to the Hockey Canada sexual assault scandal.
