is an Italian football manager and former player who was most recently the head coach of the Saudi Arabia national team.

As a player, Mancini operated as a deep-lying forward, and was best known for his time at Sampdoria, where he played more than 550 matches, and helped the team win their first Serie A league title, four Coppa Italia titles, and the European Cup Winners' Cup. He was capped 36 times for Italy, taking part at UEFA Euro 1988 and the 1990 FIFA World Cup, achieving semi-final finishes in both tournaments, although he was never put onto the pitch during the 1990 tournament. In 1997, after 15 years at Sampdoria, Mancini left the club to join Lazio, where he won a further scudetto and Cup Winners' Cup, in addition to the UEFA Super Cup and two more Coppa Italia titles. Alongside Gianluigi Buffon, he is the player with the most Coppa Italia titles (6). As a player, Mancini would often give team talks at half-time. Towards the end of his playing career he became an assistant to Sven-Göran Eriksson at Lazio.

His first manager role was at Fiorentina in 2001, at only 36 years old, winning a Coppa Italia title. The following season, he took over as manager at Lazio, where he guided the club to another Coppa Italia title. In 2004, Mancini was offered the manager's job at Inter Milan, with which he won three consecutive Serie A titles, a club record; he was dismissed in 2008. After being out of football for over a year, Mancini was appointed Manchester City manager in December 2009. He helped City win the FA Cup in the 2010–11 season, the club's first major trophy in 35 years, and their first league title in 44 years in the 2011–12 season. Mancini took over managerial duties at Turkish club Galatasaray in September 2013, winning the Turkish Cup in his only season at the club, before returning to Inter Milan for two more years before managing Russian side Zenit. In 2018, he took charge of the Italy national football team after the team had failed to qualify for the 2018 FIFA World Cup. In 2021, Mancini guided Italy to their second-ever European Championship at Euro 2020. Under his management, the team was unbeaten from October 2018 to October 2021, and holds the world record for most consecutive matches without defeat (37), but Italy then failed to reach the World Cup for the second time in a row after a play-off loss to North Macedonia.

Mancini has reached at least a semi-final of a major national cup competition in every season he has been a manager, from 2002 to 2014. He holds a number of records, including most consecutive Coppa Italia finals from 2004 to 2008, with Lazio once in 2004 and with Inter Milan in the following four seasons.
