Harry Enns (November 30, 1931 – June 24, 2010) was a Manitoba politician. He served as a Cabinet Minister in the governments of Dufferin Roblin, Walter Weir, Sterling Lyon and Gary Filmon, and was an unsuccessful candidate for the leadership of the Progressive Conservative Party of Manitoba in 1971. A long-serving member of the Manitoba legislature, he retired from public life in 2003.
The son of Reverend John Herman Enns, a minister for the First Mennonite Church, and Agathe Unruh, Enns was born in Winnipeg, Manitoba, and worked as a rancher before entering politics. He was married to Eleanor Jones. His brother Siegfried John Enns served in the Canadian House of Commons.
A Progressive Conservative, Enns was first elected to the Legislative Assembly of Manitoba in 1966, for the rural riding of Rockwood-Iberville.
In 1969, redistribution placed Enns in the riding of Lakeside, where he defeated Liberal leader Robert Bend by about 350 votes. The Lakeside riding had previously been held by former Premier of Manitoba Douglas Campbell for forty-seven years. Enns would hold the seat for a further thirty-four years, being re-elected in 1973, 1977, 1981, 1986, 1988, 1990, 1995 and 1999. After 1969, he never had any problems retaining the riding.
Enns was appointed Minister of Agriculture by Dufferin Roblin on July 22, 1967. He retained this position when Walter Weir replaced Roblin as Premier later in the year, also becoming the Acting Minister of Highways (Enns had supported Weir in the party's leadership contest). On September 5, 1968, he was moved to the Ministry of Mines and Natural Resources.
