Gheorghe "Gică" Hagi (Romanian pronunciation: [ˈɡe̯orɡe ˈhad͡ʒi] (About this sound listen); born 5 February 1965) is a Romanian former professional footballer, considered one of the best attacking midfielders in Europe during the 1980s and '90s and the greatest Romanian footballer of all time. Galatasaray fans called him "Comandante" ("The Commander") and Romanians call him "Regele" ("The King"). He is currently the owner and manager of Viitorul Constanța.

Nicknamed "The Maradona of the Carpathians", Hagi is considered a hero in his homeland. He was named Romanian Footballer of the Year seven times, and is regarded as one of the best football players of his generation. As a creative advanced playmaker, he was renowned for his dribbling, technique, vision, passing and finishing.

Hagi played for the Romanian national team in three FIFA World Cups, in 1990, 1994 (where he was named in the World Cup All-Star Team) and 1998; as well as in three UEFA European Championships, in 1984, 1996 and 2000. He won a total of 125 caps for Romania, ranked second after Dorinel Munteanu, and is the joint leading goalscorer (alongside Adrian Mutu) with 35 goals.

In November 2003, to celebrate UEFA's Jubilee, Hagi was selected as the Golden Player of Romania by the Romanian Football Federation as their most outstanding player of the past 50 years. In 2004, he was named by Pelé as one of the 125 Greatest Living Footballers at a FIFA Awards Ceremony. He was listed at number 25 in World Soccer Magazine's list of the 100 greatest players of the 20th century. Hagi is one of the few footballers to have played for both Spanish rival clubs Real Madrid and Barcelona FC.

In 2009, Hagi founded Romanian club Viitorul Constanța. He is currently both owner and chairman of the club. Hagi also established the Gheorghe Hagi Football Academy, one of the largest and most successful football academies in Southeastern Europe.

A talented left-footed attacking midfielder, Hagi's playing style was frequently compared with Diego Maradona's throughout his career, due to his technical ability as well as his temperamental character and leadership; as a youth, he was mainly inspired by compatriots Anghel Iordănescu and Ion Dumitru. A quick, highly creative, and mobile advanced playmaker, Hagi was also tactically versatile, and capable of playing in several midfield and offensive positions on either wing or through the middle, due to his ability with both feet, despite being naturally left-footed, although he had a preference for using his stronger foot; his preferred position was in a free role as a classic number 10, but he was also used as a second striker on occasion. Hagi was renowned in particular for his first touch and speed on the ball, as well as his timing, interpretation of space, bursts of acceleration, and dribbling skills, which enabled him to get past defenders; he was also highly regarded for his vision and precise passing, although he was capable of both scoring and assisting goals, and was also an accurate finisher and set-piece taker, who had a penchant for scoring goals from powerful, bending long range strikes. In spite of his small stature, Hagi possessed significant upper body strength, which, along with his control, aided him in protecting the ball from opponents, and allowed him to create space for himself or his teammates. Despite his skill and his reputation as one of the greatest number 10s of his generation, his career was marked by inconsistency at times, and he was also considered to be a controversial player, due to his rebellious and arrogant attitude, as well as his low work-rate and lack of discipline, which led him to have several disagreements with his managers, opponents, and officials.
