Sterling Trucks, a manufacturer of heavy duty trucks, was a subsidiary of Daimler Trucks North America, based in Portland, Oregon, United States, a member of the Daimler AG Truck Group. It was originally the heavy truck division of Ford Motor Company, but was purchased and rebranded in 1997. Headquartered in Detroit, Michigan, its conventional trucks were built in St. Thomas, Ontario. Sterling-brand trucks were sold in the United States, Canada, Mexico, Australia, and New Zealand.

On October 14, 2008, Daimler Trucks North America announced a plan to discontinue the Sterling product line in an effort to consolidate its North American truck manufacturing operations under the Freightliner and Western Star brands. The company stopped taking orders for new trucks in January 2009, the St. Thomas manufacturing plant closed in March 2009, and the Portland, Oregon, plant was closed in June 2010.
