The General Motors Company (GM) is an American multinational automotive manufacturing company headquartered in Detroit, Michigan, United States. It is the largest automaker in the United States and was the largest in the world for 77 years before losing the top spot to Toyota in 2008.

General Motors operates manufacturing plants in eight countries. Its four core automobile brands are Chevrolet, Buick, GMC, and Cadillac. It also holds interests in Chinese brands Baojun and Wuling via SAIC-GM-Wuling Automobile. GM also owns the BrightDrop delivery vehicle manufacturer, a namesake defense vehicles division which produces military vehicles for the United States government and military, the vehicle safety, security, and information services provider OnStar, the auto parts company ACDelco, a namesake financial lending service, and majority ownership in the self-driving cars enterprise Cruise LLC.

In January 2021, GM announced plans to end production and sales of vehicles using internal combustion engines, including hybrid vehicles and plug-in hybrids, by 2035, as part of its plan to achieve carbon neutrality by 2040. GM offers more flexible-fuel vehicles, which can operate on either E85 ethanol fuel or gasoline, or any blend of both, than any other automaker.

The company traces itself to a holding company for Buick established on September 16, 1908, by William C. Durant, the largest seller of horse-drawn vehicles at the time. The current entity was established in 2009 after the General Motors Chapter 11 reorganization.

As of January 2023, GM is ranked 25th on the Fortune 500 rankings of the largest United States corporations by total revenue.
