François Desjordy Moreau de Cabanac (1666–1726) was a soldier, seigneur and administrator in New France.
De Cabanac was stationed in Montreal until 1687 and took part in the defence of Quebec City against Major-general Sir William Phips in 1690.
[1] He was married twice: first to Anne Nolan in 1696 and then, in 1705, to Louise-Catherine, the daughter of René Robinau de Bécancour, after the death of his first wife.
In 1720, he was named town major of Trois-Rivières; his uncle Joseph Desjordy de Cabanac had held the same post from 1712 to 1713.
De Cabanac died at Trois-Rivières early in 1726 and was buried there on February 16 the same year.
