Peter George Underwood, AC (10 October 1937 – 7 July 2014) was an Australian jurist and the Governor of Tasmania from 2008 until his death in 2014.

In 2001, Underwood was awarded an honorary Doctor of Laws degree in recognition of his services to legal education, the arts and the administration of justice.

[2] On 3 March 2008, Premier Paul Lennon announced the appointment of Underwood as the next Governor of Tasmania, and he was sworn in on 2 April 2008.

[7] When the 2010 state election resulted in a hung parliament with both the Liberals and Labor on 10 seats, Lennon's successor as premier, David Bartlett, advised Underwood to commission Opposition Leader Will Hodgman as premier, as the Liberals had won a narrow plurality of the popular vote.

He also concluded that Bartlett's promise to give up power was not relevant, since the decision to invite a person to form government was solely within the governor's prerogative.

[11] Alternatively, he said, "some of the millions of dollars that will be spent on the 'Anzac Festival'" should be diverted to "support for the University of Sydney's Centre for Peace and Conflict Studies."

The speech led to scathing reactions from the national media, with columnist Andrew Bolt declaring in an editorial he was "not fit to be Governor of Tasmania".
