The Trudeau family is a Canadian political family, originating from the French colonial period, in what is now Quebec.

Two members of the family, Pierre Trudeau and Justin Trudeau, have served as the prime minister of Canada.

The Trudeau family's surname can be traced back to Marcillac-Lanville in France, in the 16th century, and to a Robert Truteau (1544–1589).

[3][4] The lineage in North America was established by Étienne Truteau (1641–1712), in what is now Longueuil (of the Canadian province of Quebec), who arrived in Canada in 1659.
