The story of organized law enforcement in Napa County begins with the very first meeting of the board of supervisors in 1850 and the appointment of a county sheriff and marshals for each township. The
foundations for progress and prosperity in place, Napa County grew from a remote agricultural outpost to the preeminent wine-growing region in the United States and a booming tourist destination�and policing
has kept pace. Today, in addition to the Napa Sheriff�s Department, the county is protected by the California Highway Patrol and three police departments: Napa, St. Helena, and Calistoga. Specialized police agencies have also grown out of unique needs, including the Napa State Hospital Police, Railroad Police, and Community College Police.
