Armand Lebrun de la Houssaye (French pronunciation: [aʁmɑ̃ ləbʁœ̃ də la usɛ]; 20 October 1768–19 June 1848) led a cavalry division during the First French Empire of Napoleon.

Promoted to general officer in 1804, he led a heavy cavalry brigade at Austerlitz, Eylau, and Heilsberg and a division at Friedland.

Transferred to Spain, he commanded a dragoon division under Marshal Nicolas Soult at Corunna, Braga, First and Second Porto, and Arzobispo in 1809.

Lahoussaye is one of the names inscribed under the Arc de Triomphe on Column 6.

When he came to Utrecht (NL) to recover, he fell in love with his neighbor's daughter, Charlotte Juliana Vossenberg.
