The Fraser Lowland is a landform and physiographic region in the Pacific Northwest of North America, shared between the Canadian province of British Columbia and the U.S. state of Washington.

The American pene-exclave of Point Roberts lies to the region's west, at the southern end of the Tsawwassen peninsula.

The rich soil, plentiful precipitation, and mild marine climate make the entire region a prime agricultural land.

Both the area and population are much larger on the Canadian side (Fraser Valley and Sumas Prairie) with about 2.4 million residents.

Other population centers on the Canadian side include Abbotsford and Chilliwack, both part of the Fraser Valley Regional District.
