Cincinnati Preservation Association (CPA) was established in 1964 as the Miami Purchase Association for Historic Preservation and renamed in 1992. The catalyzing concern was for archeological resources, which were threatened by a new power plant near Shawnee Lookout. CPA sponsored an excavation of this prehistoric site to preserve the artifacts.

The Association was responsible for creating both Historic Southwest Ohio, which manages Heritage Village Museum at Sharon Woods and the Hauck House, and the Miami Purchase Preservation Fund, which rehabilitates historic properties for housing. 
CPA was also influential in establishing the City of Cincinnati’s Historic Conservation legislation.
