The Royal Deux-Ponts Regiment (German: Deutsches Königlich-Französisches Infanteries Regiment Zweibrücken, or Royal German Regiment Zweibrücken) was a military unit which served France, raised in the Pfalz-Zweibrücken (French: Deux-Ponts). Christian IV, Count Palatine of Zweibrücken, raised and contracted the regiment to Louis XV of France in a 1751 subsidy treaty. France annexed Zweibrücken in 1797, and the Regiment was incorporated into the French Revolutionary Army and designated the 99th Infantry Regiment.
