American Cetacean Society

The American Cetacean Society (ACS) was founded in 1967 and is recognized as the first whale, dolphin, and porpoise conservation group in the world. For five decades, ACS has been dedicated to bringing education, current research, and critical conservation issues to people who care about cetaceans and the habitats on which they depend. ACS has long been the go-to resource for reliable information, with its governing board of specialists from all over the United States and its Scientific Advisory Council of internationally recognized researchers.

We are a national organization headquartered in San Pedro, California, and we see the energy and support for our mission growing daily. Our vibrant local chapters in Los Angeles, Orange County, Monterey, San Francisco, San Diego, Oregon, Puget Sound (Seattle) and our National Student Coalition host exciting monthly speakers, provide volunteer opportunities, and conduct citizen science projects to benefit cetacean education, conservation, and research.
