Leo Boccardi (born 15 April 1953) is a prelate of the Catholic Church who worked in the diplomatic service of the Holy See from 1987 until he retired in 2021, with the rank of archbishop and the title of apostolic nuncio since 2007.

He entered the diplomatic service of the Holy See on 13 June 1987 and then worked in several countries before returning to the offices of the Secretariat of State in Rome.

[1] On 24 March 2001, Pope John Paul II named him to represent the Holy See before several international organizations.

[4] Following the death of Qassem Soleimani in the 2020 Baghdad International Airport airstrike, Boccardi called for tensions to be lowered through negotiations.

He said that all parties need "to believe in dialogue, knowing from what history has always taught, that war and weapons" do not resolve the problems afflicting the world.
