The Western Connecticut Planning Region is a planning region and county-equivalent in Connecticut. It is served by the coterminous Western Connecticut Council of Governments (WestCOG), one of nine regional councils of governments in Connecticut. Within the region, there are two Metropolitan Planning Organizations, South Western CT MPO and the Housatonic Valley MPO.

The region includes the Connecticut Panhandle, Greater Danbury, and the Gold Coast. In 2022, planning regions were approved to replace Connecticut's counties as county-equivalents for statistical purposes, with full implementation occurring by 2024.[1][2]
