Who is the Pope in Italy?

The Pope of the Catholic Church is Francis, no matter where you live.

Cardinal Jorge Mario Bergoglio, Archbishop of Buenos Aires, became the 266th pope on March 13, 2013, succeeding Joseph Ratzinger (Benedict XVI). He is the first pope of the Americas, the first pope born outside Europe in more than 1000 years, and the first pope to take his name from St. Francis of Assisi.
There is only one Pope for the Catholic Church, and he is currently Pope Benedict XVI, Joseph Ratzinger of Germany; he lives in the Vatican City State, which is sovereign and not a part of Italy.

Update:
Since March of 2013 the pope is Pope Francis.
