Nationwide there are over 100 Girl Scout councils. Girl Scouts of Northern California serves 19 counties in Northern California which include: Alameda, Butte, Contra Costa, Del Norte, Glenn, Humboldt, Lake, Marin, Mendocino, Napa, Santa Clara, San Francisco, San Mateo, Shasta, Siskiyou, Solano, Sonoma, Tehema, and Trinity Counties.

Each county is further divided into Areas, and Service Units, smaller geographic regions in which our communities participate in Girl Scouting together.

Founder Juliette Gordon Low organized the first group of Girl Scouts on March 12, 1912 in Savannah, Georgia. The Girl Scouts of the U.S.A. was chartered by the United States Congress in 1950. Since then, through membership in the World Association of Girl Guides and Girl Scouts, GSUSA has grown to be part of a worldwide family of 10 million girls and adults in 148 counties.

In October of 2007, The Girl Scouts of Northern California participated in an historic national Girl Scout movement in which Girl Scout councils aligned with other councils to create high-capacity councils across the United States. Through this national “realignment”, the Konocti Girl Scout Council, the Girl Scouts of Napa-Solano, the Girl Scouts of San Francisco Bay Area, the Girl Scouts of Santa Clara County, the Girl Scouts of Sierra Cascade, and a portion of the Girl Scouts of Winema Council became the Girl Scouts of Northern California.
