Ralph Henry is the Director of Litigation at the Humane Society of the United States, where he helps oversee the largest animal protection litigation docket in the country.

Professor Henry’s past and present work in animal law has focused on protection of threatened and endangered species, marine mammals, animals trapped and farmed for their fur, and other wild animals subjected to cruel and unnecessary suffering. Professor Henry also leads HSUS’s constitutional and policy defense litigation team, and has participated in several cases concerning the constitutionality of animal protection laws in state and federal courts.

In addition to his work at the HSUS, Professor Henry regularly lectures on animal law at law schools, bar associations, and conferences around the country, and was a contributing author to the ABA-published book Wildlife Law and Ethics: A U.S. Perspective. Professor Henry also has served as an adjunct professor at the George Mason University School of Law since 2009.
