Marcel Masse should not be confused with Marcel Massé.

The Honourable Marcel Masse (born May 27 1936) is a Canadian politician.

Masse was educated at the Université de Montreal and pursued graduate work in Paris before working as a high school teacher in Joliette, Quebec from 1962 to 1966. In 1966 he was elected to the Quebec legislative assembly as a member of the Union Nationale and served as a minister in the governments of Daniel Johnson (1966-1968) and Jean-Jacques Bertrand (1968-1970). Masse ran for the leadership of the UN in 1971 but lost by 21 votes and left the party to sit as an independent until his term expired in 1973.

In 1974, Masse was hired by the engineering firm Lavelin as an administrator. He also attempted to win a seat in the Canadian House of Commons as a Progressive Conservative but was defeated in the 1974 and 1980 federal elections before winning a seat as Member of Parliament for Frontenac in the 1984 Canadian election that brought Brian Mulroney and the Tories to power.

Mulroney appointed Masse to the position of Minister of Communications . Masse resigned from the Canadian Cabinet on September 25 1985 due to an investigation by the Royal Canadian Mounted Police of alleged overspending during his election campaign but returned to Cabinet on November 30 after being cleared of any wrongdoing.

As Communications minister, Masse was responsible for Canada's cultural policy. He argued against measures that would undermine the country's cultural sovereignty during negotiations leading to the Canada-U.S. Free Trade Agreement and was moved out of the Communications portfolio to that of Minister of Energy in 1986 when it appeared to Mulroney that Masse might be an obstacle to the free trade negotiations. Masse was moved back to Communications following the 1988 Canadian election and the implementation of the Free Trade Agreement. In 1991, Masse became Minister of National Defence. He resigned from cabinet in January 1993 along with a number of other ministers who were not intending to run in the 1993 Canadian election.

Since leaving federal politics Masse, a moderate Quebec nationalist, has served in a number of positions under the Parti Quebecois governments of Jacques Parizeau and Lucien Bouchard. He was head of one of fourteen regional committees that held public hearings on Quebec independence in 1995 in the run up to the 1995 Quebec referendum on sovereignty. He served as president of the Conseil de la langue française du Québec in 1995 and then served as Quebec's delegate-general in France from 1996 to 1997. He has also served as chair of the Commission des biens culturels du Québec.
