The Cienega Watershed Partnership (CWP) is a collaborative effort aimed at sustaining the natural and cultural resources of the Cienega Watershed in Southeastern Arizona. As a funding organization, CWP receives donations and grants to support various projects and programs in the watershed area. This partnership is the result of years of community-led initiatives and the collaboration of multiple stakeholders.

The Cienega Watershed, situated in the basin bounded by the Whetstone Mountains, Santa Rita Mountains, Canelo Hills, and Rincon Mountains, is a diverse landscape of forested lands, oak-studded hills, and rolling grasslands. The watershed is predominantly federal and state lands with scattered private properties. It serves as a vital wildlife corridor connecting the Sonoran desert regions of the Southwest and northern Mexico.

Additionally, CWP focuses on the conservation and restoration of the Sonoita Valley, an area known for its scenic rolling grasslands and ranching heritage. Over the years, the valley has experienced growth and economic diversification, particularly in tourism and wineries. Through education, science, and community engagement, CWP strives to promote the shared history, natural resources, and cultural significance of the Cienega Watershed, ensuring its preservation for future generations
