Antoine Odier (15 May 1766 – 19 August 1853) was a French banker and politician. He was born in the Republic of Geneva but moved to France and was naturalized during the French Revolution (1789–99). He was involved in the Indian cotton trade before founding a banking house in Paris during the Bourbon Restoration. He was politically liberal, supported the July Revolution of 1830 and opposed the seizure of power by Louis-Napoléon Bonaparte in 1851. He favoured protectionist economic policies, and led a lobby group to oppose lowering of tariffs.
