The Secretary for Foreign Affairs (Italian: Segretario di Stato per gli Affari Esteri e Politici) is the Minister for Foreign Affairs of San Marino.
Together with the Secretary for Interior and the Secretary for Treasury, this officer is one of the three members of the executive Congress of State directly appointed by the Grand and General Council, the parliament of the republic. Due to the absence of the office of Prime Minister in the constitutional structure of the State, the Secretary for Foreign Affairs is traditionally seen as the most relevant post in the Sammarinese government.
Since 2016, the Secretary for Foreign Affairs has been Nicola Renzi of the Adesso.sm left-wing coalition.
