Charity Navigator

Charity Navigator is a charity assessment organization that evaluates more than 230,000 charitable organizations based in the United States, operating as a 501(c)(3) organization. It provides insights into a nonprofit's financial stability, adherence to best practices for both accountability and transparency, and results reporting. It is the largest and most-utilized evaluator of charities in the United States. It does not accept any advertising or donations from the organizations it evaluates.

According to a 2025 study, ratings by Charity Navigator shape donor behaviors, as donors increase their contributions to better rated charities. The study also found that charities try to achieve better ratings by cutting expenditures on administration and fundraising, as well as misreporting or mislabelling expenditures to game the ratings.
