Paul Henry Calvert, AO (born 19 January 1940) is a former Australian politician who served as a Senator for Tasmania from 1987 to 2007, representing the Liberal Party.

Born into a long established farming family based outside Hobart, Calvert still runs a property in Tasmania.

He was active in local government, serving as Warden (the title later changed to Mayor) of the City of Clarence, on Hobart's eastern shore.

In 1987 he was elected to the Australian Senate, after declining an invitation by the former Liberal Premier of Tasmania, Robin Gray, to run for the House of Assembly after a successful career in local government and agri-politics.

As part of the 2009 Queen's Birthday Honours list, he was appointed an Officer of the Order of Australia.
