Brigadier Ronald Joseph Callender Broadhurst (1906–1976) was a Northern Irish unionist politician.
In the 1973 Northern Ireland Assembly election, he was the last of seven MPAs elected in the South Down constituency, as a pro-Sunningdale candidate. He became the Deputy Speaker of the Assembly.
Also in 1973, Broadhurst appeared on Ulster Television demanding that the New University of Ulster (now the University of Ulster at Coleraine) be closed down, a request he also made in the Assembly, to no effect. As a supporter of Brian Faulkner, he followed Faulkner into the newly formed Unionist Party of Northern Ireland in 1974 and stood for the party in South Down in the Northern Ireland Constitutional Convention election of 1975 but failed to get elected.http://www.ark.ac.uk/elections/csd.htm

His papers are held in the Public Records Office of Northern Ireland in Belfast and also in St Antony's College, Oxford.
