American Humane Society

The American Humane Society, is an American animal welfare organization founded in 1877 committed to ensuring the safety, welfare, and well-being of animals. It was previously called the International Humane Association and subsequently the American Humane Association and American Humane before changing its name to American Humane Society in 2025. In 1940, it became the sole monitoring body for the humane treatment of animals on the sets of unionized Hollywood films and other broadcast productions, a role it maintains through an agreement with the Screen Actors Guild. American Humane Society is best known for its certification mark "No Animals Were Harmed", which appears at the end of film or television credits where animals are featured.
