Pembroke (2021 population 14,364; CA population 23,814) is a city in the province of Ontario, Canada, at the confluence of the Muskrat River and the Ottawa River in the Ottawa Valley. Pembroke is the location of the administrative headquarters of Renfrew County, though the city itself is politically independent. It is one-hundred fifty kilometres northwest of Ottawa.

Pembroke is the largest commercial centre between North Bay and Ottawa. Historically, forestry and farming formed the backbone of the local economy and remain important today. Local timber products include lumber, plywood, veneer, hydro poles and fibreboard. Other local manufacturing operations produce office furniture. CFB Petawawa in nearby Petawawa, Chalk River Laboratories of Atomic Energy of Canada Limited in Chalk River are also regional employers. The economy also benefits from tourism, aided partly by Pembroke’s location on the Trans-Canada Highway. Pembroke is a gateway to natural adventures on the Petawawa and Ottawa Rivers, Algonquin Park and to world-class white water rafting a short distance to the southwest.
