John Horace Dickey (4 September 1914 – 27 April 1996) was a Liberal party member of the House of Commons of Canada.
Since Halifax riding elected two members to the House of Commons at that time, Dickey joined the other incumbent, fellow Liberal Gordon Benjamin Isnor.
Isnor was appointed to the Senate in May 1950 and was joined by another Liberal, Samuel Rosborough Balcom, following a by-election the following month.
Both Dickey and Balcom were re-elected to a full term in Parliament in the 1953 election, but were defeated in the 1957 federal election by the two Progressive Conservative party candidates Robert McCleave and Edmund L. Morris.
In the 1958 election, Dickey was joined by Leonard Kitz in an unsuccessful attempt to win back the riding for the Liberals.
