Arnaud Ernest Junqua (16 February 1816 in Lectoure – 31 January 1893), was a French officer of the Légion d'Honneur, captain of the cavalry regiment of the French Imperial Guard and Chief in second of the Cent-gardes Squadron.

On 23 May 1855 he became Chevalier of the Légion d'honneur and was promoted to the rank of officer of this legion on 12 April 1864.
