George Irvine Whiteside (20 September 1902 – 27 July 1976) was an Australian politician.
Born in Victoria, he was educated at state schools before moving to Queensland to become a railway worker.
He was Queensland Secretary of the Federated Engine Drivers and Firemen's Association 1945–1962 and President of the Queensland Labor Party 1959–1960.
On 9 October 1962, he was appointed to the Australian Senate as a Labor Senator for Queensland, filling the casual vacancy caused by the death of Labor Senator Max Poulter.
The Australian Constitution dictated that a special election be held at the same time as the next federal election in 1963.
Whiteside was narrowly defeated by Liberal candidate Kenneth Morris.
