María Fernanda Silva (born 20 December 1965) is an Argentine career diplomat, and the former ambassador of Argentina to the Holy See.

[3] She studied Political Science with a specialization in International Relations at the Pontifical Catholic University of Argentina.

She then went on to study at and graduate from the Instituto del Servicio Exterior de la Nación (ISEN), Argentina's diplomatic service institute.

As Pope Francis has, since the beginning of his papacy, requested for exclusively diplomatic ambassadorships from Argentina, the new administration of President Alberto Fernández set out to look for a competent candidate for the position.

She had met Pope Francis when he was Archbishop of Buenos Aires; then-Cardinal Jorge Bergoglio had annulled Silva's marriage as her ex-husband decided to become a priest.
