A charity watchdog is a type of nonprofit organization that provides ratings of charitable groups based on how an individual charity's money is spent, how the charity governs itself, and how the charity protects its donors' privacy, among other criteria.
By country
Charity watchdog groups in the United States include Charity Navigator, CharityWatch, and the BBB Wise Giving Alliance.
In the United Kingdom, charity watchdogs include the now defunct Intelligent Giving. In 2015 the British government announced the creation of a new government-run watchdog to regulate large charities.
