Alfonso Papa (born in Naples, Italy, 2 January 1970) is a former judge, university professor and member of the Italian Parliament.

In 1993 Papa started his eight-year judiciary career as a judicial prosecutor being first assigned in Naples where he worked on cases related to drugs, terrorism, organized crime and public administration.

During his career, Papa has worked on behalf of the Italian government for the achievement of multilateral agreement inside the United Nations, the European Commission and the Organization for Security and Co-operation in Europe (OCSE).

From 2001 to 2007 he was Head of the Italian delegation for both the UN Convention against corruption signed at Mérida, Mexico and the Working Group on Bribery at OCSE.

As a member of the Justice Committee, Papa sponsored a number of provisions including the establishment of auditors in remote locations and the “empty-prisons” bill.

[9][10] On 31 October 2011, after 101 days in jail, the Court of Naples revoked his prison confinement and gave Papa house arrest stating that there was "no real danger of suppression of evidence."

On 7 November 2011 the Supreme Court struck down the order to arrest Papa declaring a lack of grounds for keeping him in confinement and the charges against him were dropped.
