Jacques-Philippe Lantier (French pronunciation: [ʒak filip lɑ̃tje]; July 21, 1814 – September 15, 1882) was a Quebec businessman, author, and political figure.

He represented Soulanges in the House of Commons of Canada as a Conservative member from 1872 to 1882.

In 1865, Lantier married Julienne Bonneville, the widow of his brother Olivier, who had been a merchant at Montreal.

Lantier published the pamphlets Canal des Cèdres (1873), The harbours of Coteau Landing and Cascades Bay (1874), and The question of the Cascades and Coteau Landing canal (1874).

In 1873, Lantier introduced a motion in the House of Commons asking for a pardon for all crimes committed in Manitoba before its entry into the Canadian union.
