is an American professional soccer player who plays as a forward for the Chicago Stars FC of the National Women's Soccer League (NWSL) and the United States women's national soccer team (USWNT).

After playing extensively at the under-17 and under-20 level, Swanson debuted for the USWNT in 2016 at age 17, becoming the team's youngest player since Heather O'Reilly in 2002. Later that year she represented the United States at the 2016 Summer Olympics in Rio de Janeiro, where she became the youngest Olympic goalscorer for the United States. She won the 2019 FIFA Women's World Cup and gold at the 2024 Paris Olympics, scoring the only goal in the Olympic final.

Swanson elected to forego her college career at UCLA to turn professional in 2017, signing with the Washington Spirit, where she stayed for three seasons before playing at Sky Blue FC. She was then traded to the Chicago Red Stars, playing in the same city as her husband, Chicago Cubs baseball player Dansby Swanson.
