Americans for Prosperity Foundation v Bonta was a United States Supreme Court case dealing with the disclosure of donors to non-profit organizations. The case challenges California's requirement that requires non-profit organizations to disclose the identity of their donors in the state tax returns. The case was consolidated with Thomas More Law Center v Bonta. In July 2021, the Supreme Court ruled in a 6–3 decision that California's requirement burdened the donors' First Amendment rights and was not narrowly tailored, and thus invalid.
