Ita Clare Buttrose (born 17 January 1942) is an Australian journalist, businesswoman, television personality and author. She was the founding editor of "Cleo", a high-circulation magazine aimed at women aged 20 to 40 that was frank about sexuality (and, in its infancy, featured nude male centrefolds) and, later, as the editor of the more conventional "Australian Women's Weekly". She was the youngest person to be appointed editor of the "Weekly", which was then, per capita, the largest-selling magazine in the world.
