2023 Westmeath Senior B Hurling Championship

The 2023 Westmeath Senior B Hurling Championship was the fourth staging of the Westmeath Senior B Hurling Championship since its establishment by the Westmeath County Board in 2020.

A total of six teams contest the Westmeath Senior B Hurling Championship. Brownstown were promoted as 2022 Westmeath Intermediate Hurling Championship winners, replacing relegated St Brigid's last year.

Relegated Cullion replaces Fr Daltons, who were promoted as Senior B champions last year. Crookedwood, Delvin, Ringtown, and St Oliver Plunkett's round out the field.

Brownstown were relegated back to the Westmeath Intermediate Hurling Championship for 2024, following a play-off defeat to Delvin.

The final was played on October 7, at TEG Cusack Park between St Oliver Plunkett's and Ringtown. St Oliver Plunkett's defeated Ringtown to win the Mickey Power Cup for the first time, and promotion to Senior 'A' for 2024.
