Pietro Parolin (born 17 January 1955) is an Italian prelate of the Roman Catholic Church. He currently serves as the Holy See's representative in Venezuela since his appointment by Pope Benedict XVI on 17 August 2009. Previously, he had served from 2002 as Undersecretary for Relations with States, the highest position in the Holy See's diplomatic service after those of Cardinal Secretary of State and Secretary for Relations with States.

Parolin was born in Schiavon, Vicenza. After he was ordained on 27 April 1980, he took up graduate studies in canon law and diplomacy. He entered the Holy See's diplomatic service in 1986 at the age of 31, and has served the Holy See as a diplomat for 20 years, in the nunciatures of Nigeria and Mexico, and in Rome as country director for Spain, Andorra, Italy, San Marino. He speaks Italian, English, French, and Spanish.

Parolin has also been at the forefront of Vatican efforts to approve and implement the Nuclear Nonproliferation Treaty. Addressing the International Atomic Energy Agency on 18 September 2006, at its headquarters in Vienna, Austria, Msgr. Parolin referred to this treaty as "the basis to pursue nuclear disarmament and an important element for further development of nuclear energy applications for peaceful purposes." He said: "Since this treaty is the only multilateral legal instrument currently available, intended to bring about a nuclear weapons-free world, it must not be allowed to be weakened. Humanity deserves no less than the full cooperation of all states in this important matter."
