The Campbell Foundation
At a glance
Key takeaways
- The Foundation funds across the United States, with priority given to Fresno, Kern, Kings, San Francisco, Tulare, Dorchester, Wicomico, Worcester, Somerset, Lancaster and York, and its work centres on watershed advocacy, community engagement, agriculture, clean and safe drinking water, water management and equitable cannabis, so check that your work matches one of these named areas before applying.
- For most applicants a modest request is realistic: about eight in ten of its grants fall between $1,000 and $90,000, the median grant is $7,500, and the Unsolicited Grants Program itself caps requests at $25,000; the single $3,300,000 grant went, as it does every year, to Resources Legacy Fund, which itself regrants to other organisations, so treat that figure as an outlier rather than a guide.
- Applying means first completing the Eligibility Checklist, which if successful leads to instructions for starting a proposal, and there are two unsolicited grant cycles a year, so plan your approach around those windows.
- Eighty-five per cent of its grant dollars went to organisations it had already funded in the two previous filings, which points to a foundation that favours relationships with organisations it already knows, though this is a share of money rather than of the number of grants made.
- The Unsolicited Grants Program will not fund a long list of categories, including academic or medical research, alcohol and drug recovery programming, animal rescue and rehabilitation, hospitals, individuals, international aid, and projects not based in the US, among others, so organisations working in these areas should not apply to that programme.

Priority Areas
The Campbell Foundation accepts proposals from US-registered 501(c)3 public charitable organisations, educational institutions and fiscally sponsored projects. Its programme areas include watershed advocacy, community engagement, agriculture, clean and safe drinking water, water management and cannabis. In agriculture, it supports collaborative conservation to improve water quality while maintaining farm viability. Its water-management work brings stakeholders together so people who depend on water, especially vulnerable and marginalised communities, can access it. Across its unsolicited grants, the Foundation is particularly interested in organisations serving diverse populations, dismantling systems that constrain individual choices and opportunities, and promoting racial equity. It prioritises organisations with established operations, multiple funders and board members, programme-aligned work, and leadership reflecting the communities they serve.
