GMC, formerly known as GMC Truck, is a brand name used on trucks, vans, and SUVs marketed in North America and the Middle East by General Motors. In January, 2007, GMC was GM's 2nd largest selling light vehicle division after Chevrolet, ahead of Pontiac.

Although GMC and Chevrolet trucks are mostly identical, their differences have varied throughout the years. While Chevrolet is marketed towards a mainstream audience, GMC vehicles are marketed as "professional grade", more upscale vehicles. Traditionally, GMCs have had different trims from Chevrolets (i.e. grille, emblems, and other minor aesthetics), larger engine options, and a generally higher price.
