Support Our Mission

Please support our vital campaigns and outreach programs.

What We Do

The mission of AAVS is to end the use of animals in science through education, advocacy, and the development of alternative methods. Founded in 1883, the American Anti-Vivisection Society (AAVS) is the first non-profit animal advocacy and educational organization in the United States dedicated to ending experimentation on animals in research, testing, and education. We work with individuals, students and parents, educators, grassroots groups, corporate and government decision makers, and members of the scientific community.
