The Friends of Connecticut State Parks, Inc. (FCSP) is an all-volunteer organization, which was formed in 1994 in partnership with the Connecticut Department of Energy and Environmental Protection, DEEP, and the Connecticut Forest & Park Association, CFPA, by members of seven nonprofit advocacy groups, each dedicated to the preservation and enhancement of a single State park in Connecticut.

The FCSP mission is to support the Connecticut state parks, forests and conservation areas through education, advocacy, and public awareness, to protect and preserve the great legacy of Connecticut natural resources and historical treasures.
