Tides Advocacy is a 501(c)(4) nonprofit that supports progressive social change through political advocacy, lobbying, and electoral engagement. It provides fiscal sponsorship, infrastructure, and strategic support to grassroots groups working on racial, gender, economic, and environmental justice. Unlike its sister organization, Tides Foundation, Tides Advocacy can engage directly in political activities. Its goal is to amplify the power of underrepresented communities to influence policy and systems change.
