Richard A. McHeffey (circa 1800 – December 5, 1874) was a political figure in Nova Scotia and a member of the Liberal Party.
He represented the township of Windsor in the Nova Scotia House of Assembly from 1838 to 1840 and was called to the province's Legislative Council in 1853.
McHeffey had long been a respected member of Nova Scotia's Liberal Party, but held no conspicuous position at the time of his appointment that would mark him for political leadership.
He nonetheless undertook the task and called at once for a meeting of the anti-confederate members of the Assembly and of the Legislative Council at Halifax.
He served as custos rotulorum for Hants County and was also a senior Grand Warden in the province's Freemasons.
