2022 Renfrew County municipal elections

Elections were held in Renfrew County, Ontario on October 24, 2022 in conjunction with municipal elections across the province.

Renfrew County Council
County council has no direct elections; its membership is made up of the mayors and reeves of the lower-tier municipalities of the county (including the reeves - rather than mayors - of Deep River, Laurentian Valley and Renfrew), while Arnpror elects a separate councillor for county council. Therefore, elections in those municipalities determine the members of council for the new term.
