César Augusto Cielo Filho (Portuguese pronunciation: [ˈsɛzɐʁ siˈelu ˈfiʎu], born 10 January 1987) is a Brazilian former competitive swimmer who specialized in sprint events. He is the most successful Brazilian swimmer in history, having obtained three Olympic medals, winning six individual World Championship gold medals and breaking two world records.

Cielo is the current world record holder in the 50-metre freestyle (long course). He received induction into the International Swimming Hall of Fame in September 2023. César Cielo is the third Brazilian to enter the International Swimming Hall of Fame, after Maria Lenk and Gustavo Borges.   

His gold medal at the 2008 Summer Olympics, in the 50-metre freestyle competition, is Brazil's only Olympic gold in swimming to date. In 2008, he broke the NCAA record in the 50-yard (46 m) freestyle (18.47 seconds) and in the 100-yard (91 m) freestyle (40.92 seconds). Cielo became the fastest swimmer in the world in the two distances, and was named NCAA Swimmer of the Year for the second year in a row.
