The Military Archbishopric of Spain (Spanish: Arzobispado Castrense de España) is a military ordinariate of the Roman Catholic Church.

Immediately subject to the Holy See, it provides pastoral care to Roman Catholics serving in the Spanish Armed Forces and their families.

The first military vicariate-general, Carlos de Borja y Centellas, was appointed in 1705, but the position lapsed in abeyance in 1930.

It was elevated to a military ordinariate on 21 July 1986 and is headed by an archbishop.

The Episcopal seat is located at the Cathedral of the Armed Forces (Catedral de las Fuerzas Armadas) in Madrid, Spain.
