Lucien Dubuc (November 29, 1877 – March 5, 1956) was a lawyer, judge and briefly a provincial level politician from Alberta, Canada.
He defeated Liberal candidate James Cornwall by an unknown number of votes.
The election however was overturned by the provincial cabinet due to significant irregularities and even going so far as to question whether the vote was held at all.
Dubuc took the matter to court to force the Executive council to recognize the results and prevent the calling of a new election.
He was appointed to the district court bench in 1920 and in 1924 Chief Justice of Northern Alberta.
