Sunlight Foundation

American nonprofit organization (2006–2020)

The Sunlight Foundation was an American 501(c)(3) nonpartisan, nonprofit organization that advocated for open government. The organization was founded in April 2006 with the goal of increasing transparency and accountability in the United States Congress, the executive branch, and in state and local governments. The foundation's primary focus was the role of money in politics. The organization sought to increase campaign finance regulations and disclosure requirements. The Sunlight Foundation ceased operations in September 2020.
