Balthazard-Annibal-Alexis Flotte de La Frédière was a soldier in New France.
The son of Jean Balthazard Flotte de La Frédière and Claudine de Chastellard, he was the nephew of the Marquis de Salières, a commander of the Carignan-Salières Regiment.
He served as acting governor of Montreal from 1666 to 1667. His name appears as Balthazard in some sources. In some lists of the governors of Montreal, his name appears as Balthazard ou (or) Annibal-Alexis.
De La Frédière had apparently been disfigured by the loss of an eye. (In some lists of the company, his brother's name appears as Annibal Alexis). The following year, he helped in the construction of Fort Sainte Thérèse.
He took part in an expedition against the Mohawks. De La Frédière was wounded during a battle with the Iroquois in 1666. A complaint was lodged by the residents of Montreal against de La Frédière for his drunkenness, immoral behaviour and for selling liquor (which was said to be of inferior quality) to the natives.
The rue de La Fredière in Saint-Jean-sur-Richelieu was named after him.
