Ottawa Valley English is Canadian English of the Ottawa Valley, particularly in reference to the historical local varieties of the area, now largely in decline. The accents of such traditional varieties are commonly referred to as an Ottawa Valley twang or brogue. The Ottawa Valley historically extends along the Ottawa River from northwest of Montreal through the city of Ottawa and north of Algonquin Park. "The Atlas of North American English" identifies an Ottawa Valley traditional dialect enclave in Arnprior, which lacks the Canadian raising of and strongly fronts before , but neither feature is documented in the City of Ottawa itself or in other nearby urban areas, which speak Standard Canadian English.
