Robin John Batterham is an Australian scientist specialising in chemical engineering. He was the Chief Scientist of Australia from 1999 to 2006.

Born in the Melbourne suburb of Brighton, Batterham graduated from the University of Melbourne in 1965 with a degree in chemical engineering, and received a PhD from the same institution in 1969.

In 1999, he was appointed Chief Scientist of Australia, a role which he undertook simultaneously to acting as chief technologist for the multinational mining company Rio Tino. Supporters of renewable energy technologies claimed that Batterham's employment by a mining company made his advice to the Prime Minster on climate change and geosequestration questionable, although Batterham assured his critics that his advice and work as Chief Scientist was neutral and not affected by his Rio Tinto position. In 2004, concern was expressed over Dr. Batterham's dual roles, and a Senate committee found that there was a conflict of interest between the two, recommending that the Chief Scientist position be made full-time. In May 2005, Batterham stepped down as Chief Scientist and took on a full-time position at Rio Tinto.

From May 2004 to May 2005, Batterham was President of the Institution of Chemical Engineers.
