Jean-Pierre-Antoine Rey (21 December 1767 - 12 January 1842) commanded a famous French infantry regiment during the Napoleonic Wars and became a general officer in 1808. He led an infantry brigade in a number of actions in Spain. His brother Louis Emmanuel Rey was a French general of brigade who also served in Spain during the Peninsular War. Since most sources do not distinguish between the generals named Rey, the two are easily confused.
