The Cardinals have elected a new Pope - and he's American.
Robert Prevost, a 69-year-old from Chicago, has taken the name Leo XIV.
He'll lead more than 1.4 billion people as head of the Catholic Church, taking over after the death of Pope Francis last month.
When addressing crowds in the Vatican for the first time following his election, the Pontiff said Catholics must try to find out how to be "a church that builds bridges".
The President and political leaders have sent their congratulations to the new Pope.
