Denis Lebel PC (born May 26, 1954) is a Canadian politician who served as mayor of Roberval, Quebec, and deputy leader of the Official Opposition.

Lebel stated that he joined the Conservatives because Prime Minister Stephen Harper recognized the Québécois nation, and maintains that he has always been a Quebec nationalist.

[1][2] On October 30, 2008, he was appointed to Harper's cabinet as minister of the Economic Development Agency of Canada for the Regions of Quebec.

[8][9] After the election, he and fellow member of Parliament (MP) Michelle Rempel proposed to become joint interim leaders of the party but ultimately lost to Rona Ambrose.

The Montreal Gazette reported on June 20, 2017, that Lebel was to be appointed as the CEO of Québec Forest Industry Council.
