J. Charles (Chuck) Guité (born 1943 or 1944 in Campbellton, New Brunswick, raised in Dugas, Quebec, on the Gaspé peninsula) is a former Canadian civil servant who was in charge of the federal sponsorship program from 1996 to 1999.
On April 2, 2004, previously confidential testimony from a 2002 inquiry into suspicious Groupaction contracts was made public. In it, Guité admits to having bent the rules in his handling of the advertising contracts but defends his actions as excusable given the circumstances, saying, "We were basically at war trying to save the country... When you're at war, you drop the book and the rules and you don't give your plan to the opposition."
He became head of federal government advertising in the 1980s, and left the public service in 1999.
