André "Dédé" Desjardins (4 July 1930 – 27 April 2000) was a Canadian union official noted for his involvement with organized crime.
Desjardins served as the president of the Conseil des métiers de la construction (transl.?Council of Construction Trades) and vice-president of the Fédération des travailleurs du Québec (Quebec Federation of Labour, FTQ) union between 1970 and 1974, becoming known as Le roi de la construction ("the king of construction").
During this time, Desjardins was involved in the scandal that led to the Cliche commission of 1974–75 headed by Judge Robert Cliche to examine corruption in Quebec construction unions.
Afterwards, Desjardins enjoyed much success as one of the leading loan sharks in Montreal until his murder.
Despite sharing the same surname, Desjardins is not related to Raynald Desjardins, a notorious mobster related to the Rizzuto crime family.
