About the Sierra Club

The Sierra Club's members are 750,000 of your friends and neighbors. Inspired by nature, we work together to protect our communities and the planet. The Club is America's oldest, largest, and most influential grassroots environmental organization.

The Sierra Club was founded in 1892 by John Muir and others, originally to protect the Sierra Nevada mountains of California. Learn more about Sierra Club history, view a timeline of the Club's accomplishments, and explore our priority issues.

Through grassroots activism, public education, lobbying, and litigation, the national Sierra Club and its hundreds of local groups work to protect the health of our environment and preserve our remaining wild places.
