Robert Barry Dickey (November 10, 1811 – July 14, 1903) was a participant in the conferences leading to the Canadian Confederation of 1867 and is therefore considered to be one of the Fathers of Confederation. From 1858 to 1867, Dickey was appointed to the Legislative Council of Nova Scotia. In 1867, he was appointed to the Senate of Canada representing the senatorial division of Amherst, Nova Scotia. A Conservative, he served until his death in 1903. His son Arthur Rupert Dickey served as a member of the House of Commons.
