Friends of Saguaro National Park (FOSNP) is a not-for-profit fundraising partner of the National Park Service, created to help preserve, protect and enhance the fragile environment and unique cultural heritage of the Sonoran Desert at Saguaro National Park.

GuideStar Gold

Since their founding in 1996, FOSNP has sought to establish collaborative relationships within the Tucson community, develop a broad donor base, and provide both funding and volunteer support for some of the park's most critical needs. The organization consistently balances its operating budget, maintains a prudent operating reserve, and devotes at least 85% of its total expenditures to programs, rather than fundraising or overhead costs. The organization's accountability and transparency has been recognized with a GuideStar Gold award.
