Henschel & Son (German: Henschel und Sohn) was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons.

The company's factories, which also manufactured narrow-gauge locomotives, were among the most important Allied bomber targets and were nearly completely destroyed.

Henschel Flugzeugwerke aircraft and missiles included: Manufacturing of trolleybuses began in 1941 and continued until 1962, ultimately totalling at least 680 vehicles,[3] while Henschel also constructed the chassis for more than 240 others that used bodies by Waggonfabrik Uerdingen [de] (which changed its name to Duewag many years later), of type ÜHIIIs and ÜHIIs.

The production was switched to commercial vehicle axles, in this area it is the largest factory in Europe.

The Kassel facility still exists and is one of the world's largest manufacturers of locomotives (Henschel Antriebstechnik).
