EarthShare is a national federation that supports leading American environmental and conservation charities.

Its stated mission is to engage individuals and organizations in creating a healthy and sustainable environment, by promoting environmental awareness and raising funds primarily through employee workplace giving.

EarthShare was founded in 1988 and currently supports more than 400 environmental and conservation nonprofits, including 39 national organizations, as well as EarthShare affiliates in 18 states (e.g., EarthShare of New York, EarthShare of New England, EarthShare of Texas). EarthShare member charities are required to meet a number of eligibility criteria. These include meeting Combined Federal Campaign requirements, spending more than 50% of their budget on environmental or conservation programs, and not advocating illegal direct action.

EarthShare has produced one of the largest environmental public service advertising media campaigns in history. Since 1992, actor and conservationist Harrison Ford lent his voice to EarthShare's public service messages promoting environmental involvement and support of environmental and conservation charities.
