The South American Under-20 Women's Football Championship (Spanish: Campeonato Sudamericano Sub-20 Femenino), officially the CONMEBOL Sub20 Femenina, is an international association football competition for women's national teams. It is held every two years for South American players under the age of 20 and serves as a qualification tournament for the FIFA U-20 Women's World Cup. In its inaugural year, 2004, it was played by U-19 players.

The last edition was held in 2022 in Chile. Brazil has won all the competitions with 9 titles in total.

For the 2002 and 2004 FIFA U-19 Women's World Championship, South America was given one qualification spot. In 2002 Brazil and Peru played a two legged play-off for one spot allocated to South America. Brazil won 12–0 on aggregate. Since 2006 South America has been given two spots for the now-renamed FIFA U-20 Women's World Cup. In this tournament, Brazil has reached the third-place match three times and Colombia reached the third-place match in 2010. Argentina has been eliminated from the group stage for all three of their appearances; Paraguay and Chile were eliminated from the group stage in their only appearance.

Sør-Amerika U20-mesterskapet for kvinner er en årlig internasjonal fotballturnering for kvinnelandslag under 20 år i Sør-Amerika. Det ble første gang arrangert i 2004 og arrangeres nå annethvert år.

Vertskapet for turneringen roterer mellom de ti medlemslandene i CONMEBOL (Sør-Amerikas fotballforbund). De fire beste lagene i turneringen kvalifiserer seg til FIFA U20-VM for kvinner.

Turneringen er en viktig plattform for unge kvinnelige fotballspillere i Sør-Amerika, og gir dem en mulighet til å representere sine land og få internasjonal erfaring. Den har også vært avgjørende for utviklingen av kvinnefotball i regionen, og har bidratt til å øke populariteten og anerkjennelsen av sporten.
