Ontario Highway 148

King's Highway 148, commonly referred to as Highway 148, is a provincially maintained highway in Ontario, Canada. The highway acts as an extension of Route 148 in Quebec, once connecting it with Highway 17, the Trans-Canada Highway, near Pembroke. It was shortened to its present terminus in 1997, and now connects downtown Pembroke to the provincial border. It follows a route that was once part of Highway 17 and Highway 62 until the Pembroke Bypass opened in 1982.

The 7.0-kilometre (4.3 mi) route of Highway 148 takes it along the Ontario shoreline of the Ottawa River from the outskirts of Pembroke to the opposite shore at L'Isle-aux-Allumettes, where it crosses the river into Quebec. The section within Pembroke is locally maintained under a Connecting Link agreement.
