The American Society for the Prevention of Cruelty to Animals (ASPCA) is a non-profit organization appeared in 1866 and dedicated to preventing cruelty to animals. The organization is based in New York. Its official mission is "to provide effective means for the prevention of cruelty to animals throughout the United States."

One of the first aims of the society was to improve and maintain the health of animals, using all possible health and scientific technologies. ASPCA is known as the first organization to establish animal hospitals in the US. ASPCA veterinarians, for example, developed the use of anesthesia and performed one of the first open-heart surgeries on animals.

ASPCA also provides for at-risk animals from around the country and helps people to take proper care of their pets, providing necessary medical care and giving advice.
