François-Xavier Malhiot (December 4, 1781 – June 12, 1854) was a merchant, seigneur and political figure in Lower Canada.

Malhiot joined the Royal Canadian Volunteer Regiment as an officer and later became a lieutenant-colonel in the militia, serving during the War of 1812.

In 1805, he married Julie Laperière and inherited land in the seigneury of Contrecoeur after the death of his father-in-law in 1807; he became principal seigneur in 1818.

In 1828, Malhiot was dismissed from his position in the militia by Lord Dalhousie after he supported resolutions critical of the governor's behaviour.

He was elected to represent Verchères (formerly Surrey) in 1830 but resigned his seat in 1832 after he was named to the Legislative Council.
