The Coats Steam Car was an American steam automobile produced from 1921 until 1923 first in Columbus and later in Sandusky, Ohio.

The car was designed by George A. Coats, but few were built. It was popular with circuses because many clowns could fit on the wide seat. It featured a three-cylinder steam engine using poppet-valves that needed water at 300 mile intervals and burned kerosene. The engine was able to build up steam pressure in 60 seconds and featured a three speed transmission with two forward and one reverse gear complete with floor shift. The car retailed for $1085.
