Western Star Trucks is a Portland, Oregon, United States based manufacturer of Class 8 commercial trucks and a subsidiary of the German Daimler AG.

Limited in production quantity compared to parent company Freightliner, Western Star specializes in trucks tailored to customer specifications. Several cab and sleeper box sizes are available, interiors can be trimmed to spec, and engines, transmissions, axles, suspensions, and brakes are available in a number of configurations. Engines used include Cummins, Caterpillar, Detroit Diesel and Mercedes-Benz diesels. As a result of this, very few identical Western Star trucks have been produced.
