9C1 is a production code used by Chevrolet to designate a vehicle intended for use as a police car or car-based emergency vehicle. 9C1-designated vehicles are marketed under the Police Pursuit Vehicle or Police Patrol Vehicle (PPV) nameplate. The 9C1 package is intended to compete with the Ford Police Interceptor and Stellantis's Dodge Charger Pursuit and Dodge Durango Pursuit.

Specific modifications and upgrades in the 9C1 package vary by vehicle platform, though they generally center around increased durability and performance. Other parts of the 9C1 package are designed to allow the installation of emergency vehicle lighting and equipment.

Considered a fleet vehicle by General Motors, the 9C1 package is considered a Special Equipment Options (SEO) code, as opposed to a Regular Production Order (RPO) code. Both groups of options are found on the production code sticker (which on most modern GM vehicles is located in the glove box).
