The Mobile Company of America was an American steam automobile manufacturer founded in 1899 by John Brisben Walker with production in Tarrytown, New York.

Walker set up the Mobile Company of America with the right to the Stanley patents but no factory, while the Locomobile Company shared the patent rights but also received the Stanley Watertown factory and most of the steam cars under production.

Manufacturing machinery was purchased and the new factory at Kingsland Point produced its first Mobile Steam carriage on March 7, 1900.

Originally built as a light runabout, Mobile added up to 24 styles of bodies to improve poor sales.

Earlier in 1900, Brisben Walker with his wife, drove a Mobile steam carriage up Pikes Peak to the timberline or approximately 10,000 feet.
