Yves "Le Boss" Buteau (1951– 8 September 1983) was a Canadian criminal and outlaw biker, known for being the first president of the Hells Angels in Canada, and was murdered by a drug dealer with ties to a rival gang, the Outlaws. He began his life of organized crime as a member of the Montreal-based motorcycle gang called the Popeyes Motorcycle Club. By the mid-1970s, he became president. Buteau would soon play a significant role in establishing the Angels as a major criminal force in Quebec.
