Animal Legal Defense Fund

For more than a quarter-century, the Animal Legal Defense Fund has been fighting to protect the lives and advance the interests of animals through the legal system. Founded in 1979 by attorneys active in shaping the emerging field of animal law, ALDF™ has blazed the trail for stronger enforcement of anti-cruelty laws and more humane treatment of animals in every corner of American life.

Today, ALDF’s groundbreaking efforts to push the U.S. legal system to end the suffering of abused animals are supported by hundreds of dedicated attorneys and more than 100,000 members. Every day, ALDF works to protect animals by:
The Animal Legal Defense Fund’s primary programs include: our Litigation Program, which files cutting-edge lawsuits to stop the abuse of companion animals, and animals abused in industries including factory farming and the entertainment business; our Criminal Justice Program, which works with law enforcement and prosecutors to seek maximum penalties for animal abusers; and, our Animal Law Program, dedicated to fostering the field of animal law among legal professionals and in law schools nationwide. Learn more about our programs here.

Since the very beginning, cutting-edge lawsuits have been at the heart of ALDF’s work to protect the lives of animals. ALDF has been at the forefront for almost three decades, pushing government agencies to do their jobs to protect animals and shining a national spotlight on issues like factory farming and dissection in schools. Read about our landmarks and victories here.

Your generous support is vital to our continued success. ALDF is a nonprofit 501(c)(3) charitable organization and relies almost entirely on individual, tax-deductible contributions from caring members and donors like you. Someday soon, U.S courts will finally accept the evidence of science and common sense — and admit that animals are sentient individuals deserving of true, legal protection. Because more than 80% of ALDF’s annual budget goes directly to our program work, your donation will go to the best possible use to bring us closer to that day.
