Marguerite Casey Foundation is a Seattle-based philanthropic fundraising organization focused on advancing policies and practices that address the needs of people and communities that have been excluded or underrepresented. Operating in the philanthropic sector, it supports initiatives and partnerships intended to make government and the economy more inclusive. Its aim is a democracy and economy that reflect the contributions and aspirations of marginalized communities, rather than merely representing them. The foundation emphasizes belonging and representation, trust, and mutual respect as guiding values in its work with partners and grantees. In 2026 it established a notable partnership with the Guardian group as part of the Building Power project.
