Volunteer in The Humane Society of the United States

We are Humane World for Animals. Formerly called the Humane Society of the United States and Humane Society International.

Since 1954, we have worked to create a more humane society for animals. Working side by side as the Humane Society of the United States and Humane Society International, we’ve helped to pass thousands of landmark laws, rescued hundreds of thousands of animals, and cared for and protected millions more.

In 2025, to convey our mission and make sure that everyone understands who we are and the bold work that we do, our organizations are standing together under a new shared name: Humane World for Animals.

Since 1954, you’ve helped us take on the biggest fights for animals across the country and around the world. The major issues impacting animals have changed over the years, but our mission remains the same: To create a more humane society.
