National Anti-Vivisection Society

Vivisection (vi-və-ˈsek-shən)
n. The practice of cutting into or using invasive techniques on live animals. Derived from the Latin vivus, or alive, vivisection is commonly called animal experimentation, and includes the use of animals for research, testing and education.


Founded in 1929, the National Anti-Vivisection Society (NAVS) has a proud history of animal advocacy aimed at ending the cruel and outdated practice of animal experimentation.

Working With Scientists

By promoting positive solutions that will replace cruel, costly and flawed animal experiments with modern, human-relevant innovative methods of research, safety testing and education, NAVS’ animal advocacy efforts will save not only animal lives, but human lives as well.
NAVS works with scientists from academia, government and industry to develop and implement smarter, research methods that replace the use of animals through funding of the International Foundation for Ethical Research (IFER) and other promising collaborations with the scientific community.

Working to End Classroom Animal Dissection

NAVS’ animal advocacy extends to the classroom, as well. By supporting the integration of today’s technology into science classrooms—including safer, cost-effective educational resources to replace animal dissection—NAVS aims to make the life sciences more exciting as well as more humane.. And by recognizing humane science achievements at international science fairs, NAVS is providing positive incentives for future generations of researchers to advance science without harming animals.


NAVS is also helping to support and advance state and federal legislation that would have a positive impact on animals. Through our online animal advocacy center, NAVS empowers individuals to make a positive difference by providing timely information on pending legislation and ways animals are used in science so they can easily take action, spread the word, and make informed, compassionate choices.

Helping Animals

And NAVS’ animal advocacy efforts don’t end at the laboratory door. The NAVS Sanctuary Fund advances greater compassion for animals by providing emergency financial assistance to support animals retired from laboratories and those threatened by natural and man-made disasters.
