Northwest Ohio, or Northwestern Ohio, consists of multiple counties in the northwestern corner of the US state of Ohio. This area borders Lake Erie, Southeast Michigan, and northeastern Indiana. Some areas are also considered the Black Swamp area. The Toledo metropolitan area is part of the region.

Northwest Ohio's population in 2000 was 1,639,144 and is declining, specifically in the northern regions (counties shaded in the darker blue and Allen County). However, southern areas, such as Marion and Morrow counties, and the city of Findlay are growing.

Largest municipalities Toledo is the principal city of Northwest Ohio. Most of the region's television channels and radio stations are licensed in Toledo, Perrysburg or nearby Bowling Green. Though Toledo is an industrial city, Northwest Ohio is primarily agricultural with small centers of commerce distributed across region. Since the 1970s, the population of Lucas County and the Toledo metropolitan area has declined, though Wood and Hancock counties have had moderate population growth.
