A.G.S. (Automobili G. Alfieri & C.) was an Italian automobile manufacturer active from 1925 to 1927, based in Milan. Founded by Giuseppe Alfieri, the company specialized in the production of small sports cars. The vehicles were characterized by their low profile and innovative design, which included independent suspension on all wheels.

The A.G.S. cars were powered by a 1093cc Chapuis-Dornier engine, providing a blend of performance and agility. In 1927, Alfieri developed a competition model featuring a Cozette-supercharged 1084cc S.C.A.P. engine; however, only one unit of this model was produced, which was later modified for road use. Overall, the production of A.G.S. vehicles was very limited, reflecting the niche market the brand occupied during its brief existence.
