Gordon Page Barton (30 August 1929 – 4 April 2005) was an Australian businessman and political activist.

He showed his intelligence and originality early, at the University of Sydney, where he found by careful study of the handbook of course requirements he could select a particular group of subjects that would qualify him for three degrees simultaneously, in the time normally taken for one.

[citation needed] While still at university Barton started Interstate Parcel Express Company (IPEC), which was the core of his business.

In 1967, he formed the company Tjuringa Securities which was the pioneer Australian corporate raider.

Until their separation and estrangement, their blended family included Barton's two children and Ayrton's daughter Kate.
