The Rio Grande Chapter of the Sierra Club, based in Albuquerque, New Mexico, is a vibrant, volunteer-led organization that represents over 7,000 members across New Mexico and West Texas. Established in 1963, the chapter focuses on exploring, enjoying, and protecting the planet, with an emphasis on climate action, clean air and water, and the conservation of wildlife and public lands. The chapter comprises four regional groups: Northern New Mexico, Central New Mexico, Southern New Mexico, and El Paso, each contributing to leadership and decision-making within the chapter's Executive Committee.

The Rio Grande Chapter engages with a variety of environmental issues, including climate change, public lands, and social justice, while offering opportunities for volunteering, outdoor events, and educational programs like the Military Outdoors Program and the Sierra Student Coalition. Committed to driving positive change, they encourage community involvement through membership, donations, and active participation in local and state elections. The chapter strives to inspire collective action for a sustainable future.
