Iran Press/Europe: Mancini's original contract was set to expire after the 2022 World Cup in Qatar, and the new deal will see him stay on until the 2026 edition.
"We wanted to give continuity to our work. Beyond winning a trophy, there's a project to work on," Gravina said.
"Mancini has been working brilliantly for two years and moving forward on this project was a duty out of respect for the federation and our fans," he added.
Mancini was appointed Italy manager in May 2018 after they failed to qualify for the 2018 World Cup.
