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. Highway 148 follows a route that was once part of Highway 17 and Highway 62 until the Pembroke Bypass opened in 1982.

Route 148 is an east-west highway in Quebec, Canada. It runs from junction of Autoroute 13 and Autoroute 440 in Laval in the Montreal region to the Ontario-Quebec border in L'Isle-aux-Allumettes in western Quebec. For most of its length, Route 148 follows the north shore of the Ottawa River where it acted as the principal route between communities in the Outaouais region until the completion of Autoroute 50 in 2012. At the Ontario-Quebec border in L'Isle-aux-Allumettes Route 148 continues into Ontario as Highway 148.
