Gérard D. Levesque, Canadian lawyer and politician, 5th Deputy Premier of Quebec (b. 1926)
Gérard D. Levesque (May 2, 1926 – November 17, 1993) was a longtime Quebec politician and Cabinet minister, who twice served as interim leader of the Quebec Liberal Party.

Levesque was first elected to what is now called the Quebec National Assembly in the riding of Bonaventure in 1956 and sat in the legislature continuously until the end of his life. Under Premier Jean Lesage he served as minister of housing and fisheries and then as minister for trade. In the first cabinet of Robert Bourassa, who came to power in 1970, he served in various capacities including minister of trade, Minister of Justice and deputy premier.

After the defeat of the Bourassa government in 1976, Levesque served as Leader of the opposition until 1979, while leaders Robert Bourassa and then Claude Ryan were without parliamentary seats. Levesque was noted for his fierce opposition to what was introduced as Bill 1, the Charter of the French Language; his procedural wrangling meant it had to be eventually reintroduced as Bill 101. Levesque was also interim leader of the party between Bourassa's resignation and the election of Ryan. Levesque again served as Leader of the Opposition and acting leader of the party from August 1982 to September 1983 after the resignation of Ryan and until the return of Bourassa for his second stint as party leader.

In the second Bourassa government, elected in 1985, Levesque served as minister of finance, a position he held until his death in 1993 at the age of 67.
