Robert Logan Dean (born 31 October 1952) Australian politician is a former member of the Victorian Legislative Assembly.
In 1992, Dean, a long-time Liberal Party activist, obtained preselection for the marginal Labor Party seat of Berwick; and, in the wake of the 1992 Kennett landslide, he easily defeated former Treasurer Robert Jolly.
In October 2002, Robert Doyle launched a successful coup against Napthine's leadership.
However, the following month it emerged that Dean had failed to update his address after he moved out of his residence in Berwick after his preselection victory for Gembrook.
[1] Labor went on to a landslide victory, winning the most seats they have ever won at the state level in Victoria.
