Ian Gibson (26 September 1938 – 9 April 2021) was a British Labour politician and scientist who served as Member of Parliament (MP) for Norwich North from 1997 to 2009. Gibson was a professor at the University of East Anglia prior to his election to Parliament and was considered one of the country's leading cancer experts. He chaired the Science and Technology Committee in the House of Commons from 2001 to 2005 and came into conflict with the Blair government due to his left-wing views. He resigned from the Commons in 2009 after being barred from standing as a Labour candidate in the 2010 general election, due to his behaviour during the parliamentary expenses scandal.
