Omineca River is a river of the North American boreal forest, in northern British Columbia, Canada.
It flows into Williston Lake, and is part of the Peace River basin.
It was originally a tributary of the Finlay River before the creation of Lake Williston.
According to Father Adrien-Gabriel Morice the name is derived from a Sekani word meaning 'lake-like or sluggish river'.
