Ada Aline Urban (15 May 1868 – 2 October 1937) was a British film company executive. She funded the Kinemacolor business established by her husband Charles Urban, helping it achieve global distribution as the first successful motion picture natural colour system. She became director of the Natural Color Kinematograph Company, which produced Kinemacolor films, as well as other of her husband's film companies. According to the Women Film Pioneers project of Columbia University Libraries, "she was the leading female figure in British film of her day".[1]
