Auto-Dynamic Company was an American automobile manufacturer based in New York City, active from 1900 to 1902. The company specialized in the production of electric vehicles and was notable for its in-house battery manufacturing capabilities.

During its brief existence, Auto-Dynamic offered a variety of body styles for its electric cars, including a four-seater trap, brougham, hansom cab, and delivery wagon. These models reflected the early 20th-century interest in electric transportation, which was seen as a cleaner alternative to steam and gasoline-powered vehicles.

Despite its innovative approach, Auto-Dynamic ceased operations after just two years, contributing to the early landscape of electric vehicle development in the United States.
