Jean-Jacques Bertrand (French pronunciation: [ʒɑ̃ ʒɑk bɛʁtʁɑ̃]; June 20, 1916 – February 22, 1973) was a Canadian politician and lawyer who served as the 21st premier of Quebec, from October 2, 1968, to May 12, 1970.

In 1966, the Union Nationale was put back in office and Premier Daniel Johnson, Sr. appointed Bertrand to his Cabinet.

His victory (58% of the delegates) over colleague Jean-Guy Cardinal (41%), Minister of Education and newly elected MLA for the district of Bagot, at the Leadership Convention of 1969, caused a deep division among party insiders.

Two Union Nationale MLAs, Jérôme Proulx and Antonio Flamand crossed the floor and sat as Independents, along with Parti Québécois Leader René Lévesque and Liberal dissident Yves Michaud to protest against the new law.

The less controversial accomplishments of the Bertrand administration include the abolition of the Legislative Council of Quebec, the provincial equivalent of the Canadian Senate.
