Iain Stewart (1964- ) is a Scottish geologist and former child actor. However, he gave up his acting career to study geology and geography and eventually received a PhD. No doubt assisted by his acting experience Dr Stewart has gone on to present a number of science programmes on television. The first of which was Helike: The Real Atlantis (2002), in which he proposed that the submergence of Helike was the inspiration for elements of Plato’s Atlantis story^(a).

He was a member of the steering committe of the 2008 Atlantis Conference held in Athens.

Stewart now lectures on geology at the University of Plymouth. In 2007 a newly identified species of ant, Cerapachys iainstewarti, was named after him, when it was discovered during the filming of a TV programme presented by him.
