Médéric Martin (22 January 1869 – 12 June 1946) was a Canadian politician and long-time Mayor of Montreal.

Born to Salomon Martin, a carpenter and Virginie Lafleur, Martin studied at St. Eustache College and went on to open a cigar store in Montreal's East End and soon became a populist politician, best known for stirring up suspicion against English Montreal residents.

Martin oversaw the city during a period when several other adjacent municipalities were merged, including Notre-Dame-de-Grâce and much of the predominantly French speaking east side.

He considered Montreal's new French-demographic dominance to be justification for discontinuing the longstanding tradition of alternating mayors between English and French speakers, a practice that has never returned.

Martin was appointed to the Legislative Council of Quebec in 1919 and represented the district of Alma.
