Every year on the third Friday in May, thousands of people around the world participate in Endangered Species Day by celebrating, learning about, and taking action to protect threatened and endangered species. This global day of action and celebration was created and founded by David Robinson and the Endangered Species Coalition in 2006, and has continued ever since.

Along with the 18th annual Endangered Species Day, 2023 also marks the 50th Anniversary of the Endangered Species Act (ESA), a landmark piece of legislation that institutionalized our national commitment to the conservation of fish, plants and wildlife and the places they call home.

On Endangered Species Day 2023, wildlife refuges, gardens, schools, libraries, museums, community groups, nonprofits, and individuals will hold special programs or events. People around the world participate in these activities and others. Join us in celebrating Endangered Species Day and the 50th Anniversary of the ESA on Friday, May 19th and throughout the month of May!
