WBACH was a radio network in the American state of Maine, active from 1991 to 2017. Airing on four stations at its peak, the network broadcast a classical music format from studios in Kennebunk. Following the bankruptcy of Nassau Broadcasting Partners in 2011, the network's stations were sold off and largely converted to translators of other radio stations. The WBACH format and branding remained on one of the former network's stations, WBQX in Thomaston, and was added in 2013 to a new translator in Portland. The stations dropped the classical format in 2017.
