The Ecologic Foundation is an environmental organisation in New Zealand.
The Society had its origins in the Beech Forest Action Committee and the Native Forest Action Council (NFAC). In 1989 the NFAC changed its name to the Maruia Society: "Maruia" means "sheltered valley" in the Māori language, and there is also a valley of that name in New Zealand's South Island. In 1999, the society adopted an altered mission and took the name Ecologic Foundation.
Throughout most of its history, the executive director was Guy Salmon who has been present through all the group's incarnations.
