2021 South American U-17 Championship

The 2021 South American U-17 Championship was originally going be the 19th edition of the South American U-17 Championship (CONMEBOL Sudamericano Sub-17), the biennial international youth football championship organised by CONMEBOL for the men's under-17 national teams of South America. It was scheduled to be held in Ecuador between 31 March – 25 April 2021, before its suspension and subsequent cancellation due to the COVID-19 pandemic.

On 22 December 2020 CONMEBOL announced that the tournament would be rescheduled to the second half of 2021 if FIFA decided to cancel the 2021 FIFA U-17 World Cup, which was confirmed two days later. On 28 December 2020, CONMEBOL confirmed the rescheduling of the tournament, despite the fact that the Colombian Football Federation had announced its cancellation, with October as a possible tentative date and keeping Ecuador as the host country. Eventually, CONMEBOL decided to cancel the tournament during a meeting of its council held on 3 August 2021.

As the 2021 FIFA U-17 World Cup was cancelled due to the COVID-19 pandemic, this tournament would not have served as qualifier for any FIFA U-17 World Cup. Originally the top four teams would have qualified as the CONMEBOL representatives, together with Peru which would have qualified automatically as the World Cup hosts (fifth-placed team would also have qualified if Peru were among the top four).

Argentina are the defending champions.
