Ronaldo de Assis Moreira (born 21 March 1980), commonly known as Ronaldinho Gaúcho or simply Ronaldinho, is a Brazilian professional footballer who plays as an attacking midfielder or left winger for Serie C side Ravenna. Widely regarded as one of the greatest players of all time, he won two FIFA World Player of the Year awards and a Ballon d'Or. He is the only player ever to have won all of the following: a World Cup, a Copa América, a Confederations Cup, a Champions League, a Copa Libertadores and a Ballon d'Or. A global icon of the sport, Ronaldinho was renowned for his dribbling abilities, free-kick accuracy, his use of tricks, feints, no-look passes, and overhead kicks, as well as his ability to score and create goals. Also known by the nickname "O Bruxo" ('The Wizard'), during his career, he was one of the most valuable sportsmen in the world.
Ronaldinho made his career debut for Grêmio, in 1998. Aged 20, he moved to Paris Saint-Germain in France, where he established himself as one of the best players in Ligue 1. In 2003, he signed for Barcelona, where he experienced his prime years, winning his first FIFA World Player of the Year award as Barcelona won the 2004–05 La Liga title. In the season that followed, he was integral to Barcelona winning their second ever UEFA Champions League and another La Liga title, giving him his first career double. Ronaldinho received the 2005 Ballon d'Or and his second World Player of the Year in the process. Due to these successes, Ronaldinho is widely credited with rejuvenating Barcelona in the early 2000s.
Following a second-place La Liga finish to Real Madrid in the 2006–07 season and an injury-plagued 2007–08 season, Ronaldinho suffered a decline in his performances—due to a decrease in dedication and focus towards football. In 2008, he departed Barcelona to join AC Milan, where he was part of the squad that won the 2010–11 Serie A. He returned to Brazil to play for Flamengo in 2011 and Atlético Mineiro a year later where he won the 2013 Copa Libertadores, before moving to Mexico to play for Querétaro and then back to Brazil to play for Fluminense in 2015. In 2026, he came out of retirement to play for Ravenna.
Ronaldinho accumulated numerous other individual awards in his career: he was included in the UEFA Team of the Year and the FIFA World XI three times each, and was named UEFA Club Footballer of the Year for the 2005–06 season and South American Footballer of the Year in 2013; in 2004, he was named by Pelé in the FIFA 100 list of the world's greatest living players. In 2009, World Soccer magazine voted him World Player of the Decade 2000s.
In his international career with Brazil, Ronaldinho earned 97 caps, scored 33 goals, and represented them in two FIFA World Cups. After debuting with the Seleção by winning the 1999 Copa América, he was an integral player in the 2002 World Cup winning team, positioned alongside Ronaldo and Rivaldo in an attacking trio, and was named in the World Cup All-Star Team. He captained his team to the 2005 FIFA Confederations Cup title and was named man of the match in the final. He also captained the Brazil Olympic team to a bronze medal in men's football at the 2008 Summer Olympics.
