The Hummer H3 was a full-size off-road SUV or truck model produced and sold by General Motors (GM), unlike the H1 and H2, which were made by the heavy vehicle and military contract automotive manufacturer AM General.

The third and smallest model in the original Hummer truck and SUV lineup, the Hummer H3 was introduced in 2005 for the 2006 model year. The Hummer H3 was based on the platform used to build the Chevrolet Colorado and the GMC Canyon trucks, though reworked for heavy-duty operations and off-road duties. During its run, the large SUV competition of the Hummer H3 included the Chevrolet Avalanche, the Dodge Nitro, the Jeep Commander and Wrangler, the Nissan Xterra, the Toyota 4Runner and FJ Cruiser, and the Toyota Tacoma.

The Hummer H3 was discontinued after its 2010 model year due to its poor fuel economy ratings as gas prices skyrocketed. However, the Hummer nameplate will be returning under the GMC marquee of GM as the GMC Hummer EV lineup of electric trucks and SUVs.
