The Hospital Association of Southern California is a regional association in the hospitals and health care sector, based in Los Angeles, California. It represents 182 hospital members through 35 health systems across Los Angeles, Orange, Riverside, San Bernardino, Santa Barbara, and Ventura counties. Its mission is to advocate for hospitals while promoting the health and well‑being of the communities they serve.

Membership work and industry collaboration define its activities, with partnerships and endorsed business-partner programs shaping its approach to workforce and care delivery. In early 2026, its endorsed partner GreenRock Capital LLC pursued several collaborations with regional organizations to advance apprenticeships and related workforce initiatives, and to participate in events such as the California Care Collaboration Conference. These efforts illustrate how HASC connects hospitals with workforce, public health, and community organizations to address regional needs.
