Ted R. Smith (1906–1976) was an American aircraft designer. He worked for the Douglas Aircraft Company, Aero Design and Engineering Company, and Rockwell Standard Corporation. In 40 years, his designs included the Douglas A-26 Invader (under the direction of Ed Heinemann), and the first all metal small twin engine business aircraft for Aero Commander, a company that he helped to start. The Aero Commander line included one of the first twin engined business jets, the Jet Commander. In the 1960s he designed and manufactured the Aerostar line, under his own name. The Aerostar was later built by Piper Aircraft, as the Piper Aerostar.
