Aldo Andretti (February 28, 1940 – December 30, 2020) was an Italian-born American racing driver and entrepreneur, the twin brother of Mario Andretti and the father of Carolyn Andretti Molander, Mark Andretti, John Andretti, Mary Jo Andretti Dial, and Adam Andretti. He was the uncle of Michael Andretti and Jeff Andretti, great-uncle of Marco Andretti, and grandfather of Jarett Andretti. Aldo and Mario were identical twins. However, due to facial reconstructive surgery following a major racing accident, Aldo did not look identical to Mario.
