List of primary highways in Catalonia
The network of primary highways in Catalonia, Spain, can be divided into two groups: highways managed by the Spanish Government and highways managed by the Generalitat de Catalunya.
The first group are itineraries included in the Red de Interés General del Estado, which generally either serve as long-distance connectors beyond the Catalonia's field or either have a special strategical importance. They are mainly autopistas or autovías but some regular roads can also be found.
The second group are itineraries mainly used for Catalonia's internal transport. However, some of these highways are main communication paths and suffer from heavy traffic.

Primary highways managed by the Generalitat de Catalunya
The primary highways managed by the Catalan Government serve mainly for transport inside Catalonia.Since year 2004, their denomination follows the next rules:
- The letter C before the hyphen means that the road is managed by the Generalitat de Catalunya
- The first number after the hyphen indicates the main bound:
- *1 for south-northbound highways
- *2 for west-eastbound highways
- *3 for southwest-northeastbound highways
- *4, 5 and 6 for southeast-northwestbound highways
- The second number after the hyphen indicates the ordinal number within the category indicated by the first number. For example, for south-northbound highways, the lowest number correspond to the westernmost highway, whereas the highest number is for the easternmost one.
