Croizemarie was a French automotive manufacturer that operated sometime after the turn of the 20th century. During this time, there were estimated to be over 1,000 independent car makers operating in France. Many of these automakers only created one car, making it difficult to track the history of every company. Croizemarie is one of these forgotten brands. Unknown until 1999, when the only known Croizemarie car, the Type AC, appeared at auction. This car was powered by a single cylinder De Dion 5hp engine, and featured a three speed manual transmission.
