Cascade AIDS Project

Cascade AIDS Project (CAP) is a nonprofit organization based in Portland, Oregon, in the United States. Its mission is to prevent HIV infections, to "support and empower" people affected and by HIV/AIDS, and to eliminate stigma associated with the disease. Founded in 1983 and incorporated two years later, CAP is the "oldest and largest community-based provider of HIV services, housing, education and advocacy" in Oregon and Southwest Washington.

In 2017, Prism Health opened as an extension of CAP.
