Portugalske oružane snage (Portugalski: Forças Armadas Portuguesas) se sastoje od Mornarice (Marinha), Kopnene vojske (Exército) i Zračnih snaga (Força Aérea). Formalni je komandant Predsjednik Portugala, ali u praksi vojska odgovara vladi, i to preko Ministra odbrane. Zadatak oružanih snaga je očuvanje teritorijalnog integriteta zemlje i njenih prekomorskih teritorija ko i učestvovanje u međunarodnim misijama pod patronatom UN-a i NATO-a. Skorije operacije uključuj učešće u ratu u Afganistanu, intervencije u Istočnom Timoru i Gvineji Bisao te misijama na Balkanu i Libanonu. Prekomorske baze i garnizoni se nalaze na Madeiri i Azorima. Trenutno portugalske oružane snage maju oko 45.000 pripadnika od kojih je većina u Kopnenoj vojsci.
