Pierre "PK" Vallières (22 February 1938 – 23 December 1998) was a Canadian journalist and writer, known as an intellectual leader of the Front de libération du Québec (FLQ).

[3] Vallières had been working for La Presse for two years when he was fired for taking part in "subversive activities", having become a left-wing political activist at a young age.

While in New York, Vallières was held in the Manhattan House of Detention for Men before being extradited back to Canada, where he was immediately arrested in connection with the robbery of a Montreal cinema on 27 August 1966.

[7] Vallières wrote a number of works during his four-month imprisonment in New York in 1967, the most famous of which was Nègres blancs d'Amérique (1968), translated into English as White Niggers of America.

The following year, Vallières renounced violence as a means to achieve Quebec independence, and on 4 October 1972, under a plea bargain agreement, received a one-year suspended sentence on three charges of counselling kidnapping for political purposes.
