Northwest or
northwestern Ohio consists of multiple counties in the northwestern corner of the
United States state of
Ohio. This area borders
Lake Erie, southern
Michigan, and eastern
Indiana. Some areas in northwestern Ohio are also considered the
Black Swamp area. The
Toledo metropolitan area is also part of the region. Just like any other region, there is no universally agreed-upon boundary for northwestern Ohio, as the entire area is defined differently by the opinions of multiple people.
