In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the region. Such regions are not legally incorporated as a city or town would be and are not legal administrative divisions like counties or separate entities such as states. As a result, sometimes the precise definition of a given metropolitan area will vary between sources. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as a metropolitan statistical area in 1983.

This is a list of former high school athletic conferences in the Northwest Region of Ohio, as designated by the OHSAA. If a conference had members that span multiple regions, the conference is placed in the article of the region most of its former members hail from. Because the names of localities and their corresponding high schools do not always match and because there is often a possibility of ambiguity with respect to either the name of a locality or the name of a high school, the following table gives both in every case, with the locality name first, in plain type, and the high school name second in boldface type. The school's team nickname is given last.
