American Humane Society

The American Humane Society (previously American Humane), is an American animal welfare organization founded in 1877 that works to rescue, care for, and protect animals by taking action wherever and whenever they are in need. 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.

The organization also rescues animals following natural disasters, reunites retired Military Working Dogs with their former handlers, and celebrates pups who do extraordinary things at the Hero Dog Awards. Additionally, American Humane Society supports conservation work, and runs programs that certify farms, zoos, and aquariums, among other institutions for the humane treatment of animals.

The American Humane Society Science and Standards Department works across all of the group’s activities to ensure animal welfare standards align with the latest research and science.

American Humane Society is headquartered in Washington, D.C. It is a section 501(c)(3) nonprofit organization.
