Erich Bitter Automobil GmbH (Bitter) is a premium sports-luxury automobile marque produced in Germany and later Austria. Founder Erich Bitter, a former racing driver turned automobile tuner, importer, and ultimately designer began crafting his own vehicles after business ventures with Italian manufacturer Intermeccanica ended.

Bitter specializes in rebodying other manufacturers' vehicles and its initial production was between 1973 and 1989, selling vehicles in Europe and the United States. Thereafter, several prototypes followed with possible future low-volume production, but none arrived until the launch of the Bitter Vero in 2007.
