Charles Downey Hardy (12 December 1898 – 27 August 1941) was an Australian politician who served as a Senator for New South Wales from 1932 to 1938, representing the Country Party.

Allegations later surfaced that Hardy may have been attempting to organise a paramilitary movement along the lines of the New Guard, possibly preparing for a coup against the state government.

[2] He did not regularly attend the Senate chamber and described it as "simply an echo of city interests that have more than their fair share of representation".

In May 1941, Hardy was appointed as a business liaison officer to the Department of Air, working in an honorary capacity and supervising construction expenditure.

A memorial service was held on 31 August at St Alban's Church, Lindfield, with Prime Minister Arthur Fadden in attendance.
