Kamilla Soares Cardoso (born 30 April 2001) is a Brazilian professional basketball player for the Chicago Sky of the Women's National Basketball Association (WNBA) and the Guangdong Vermilion Birds of the Women's Chinese Basketball Association (WCBA). She played college basketball at Syracuse and South Carolina. She won two national championships with South Carolina in 2022 and 2024, and was named NCAA Tournament MOP in 2024. Cardoso was selected third overall in the 2024 WNBA draft by the Chicago Sky.

A native of Montes Claros, Brazil, Cardoso played high school basketball for Hamilton Heights Christian Academy in Chattanooga, Tennessee. As a senior, she averaged 24.1 points, 15.8 rebounds and 9.2 blocks per game. Cardoso was selected to play in the McDonald's All-American Game and the Jordan Brand Classic. Rated a five-star recruit and the number five player in her class by ESPN, she committed to playing college basketball for Syracuse over offers from UConn, Ohio State, Mississippi State and South Carolina. She was the highest-rated recruit in program history.

As a freshman at Syracuse, Cardoso was the team's starting center and averaged 13.6 points, eight rebounds and 2.7 blocks per game, becoming the first player in program history to win the Atlantic Coast Conference (ACC) Freshman of the Year award. She shared ACC Defensive Player of the Year honors from the league's coaches with Lorela Cubaj and was named first-team All-ACC by the Blue Ribbon Panel. Following the season, Cardoso transferred to South Carolina. As a sophomore, she was a reserve for Aliyah Boston, averaging 5.4 points and 5.1 rebounds per game and helping her team win the national championship. In her junior season, Cardoso averaged 9.8 points and 8.5 rebounds per game off the bench. She was named Southeastern Conference (SEC) Sixth Woman of the Year and second-team All-SEC.

On 7 April 2024, Cardoso was named the NCAA basketball tournament Most Outstanding Player following a dominant 15-point, 17-rebound performance in her team's 2024 national championship win. Cardoso graduated shortly after the 2024 WNBA draft, having majored in psychology.

Cardoso was selected 3rd overall in the 2024 WNBA draft by the Chicago Sky. In her first pre-season game against the Minnesota Lynx, Cardoso suffered a shoulder injury that caused her to miss the first six games of the 2024 WNBA season. She made her debut on 1 June, posting 11 points and 6 rebounds off the bench in 18 minutes in a 70–71 loss to the Indiana Fever. After the Sky starting center Elizabeth Williams suffered a season-ending knee injury, Cardoso was slotted into the starting lineup. On 8 June, she made her debut as a starter and recorded 13 points and 5 rebounds in 21 minutes in a 71–80 loss to the Atlanta Dream. Cardoso's season ended prematurely as she re-aggravated her shoulder injury and did not play in the last two games. In her rookie season, Cardoso averaged 9.8 points, 7.9 rebounds and 1.4 blocks, and ranked second in the league (behind teammate Angel Reese) in offensive rebounds per game at 3.0. After the season, she was named to the WNBA All-Rookie Team.

In the 2025 season, Cardoso appeared in 40 games, starting 39. On 24 June, she scored a career-high 27 points in a 97–86 win against the Los Angeles Sparks. She then missed the next four games to join Brazil for the 2025 FIBA Women's AmeriCup. Overall, in her second season, she averaged 13.6 points, 8.5 rebounds, and 2.5 assists per game (all career-highs).
