Bárbara de Kassia Godoy Domingos (born 2 March 2000) is a Brazilian individual rhythmic gymnast.

She is the 2023 Pan American Championships all-around champion, the 2023 Thiais Grand Prix ribbon gold medalist, and the first Brazilian rhythmic gymnast to qualify for the individual all-around final at the World Championships.

In 2018, at the South American Games in Cochabamba, Domingos won gold with ball, and silver in all-around, hoop and ribbon.

This placement meant that she fell short of winning a spot to compete at the 2020 Summer Olympics, which went to gold medalist Rut Castillo.

At the end of the year, she underwent surgery for a hip injury and was unable to train for six months.

[6] In September, Domingos competed at the Pan American Games in Santiago, winning gold in all-around, ball and ribbon, and silver in hoop and clubs.

[16] During the final, she struggled with her first routine, hoop, including letting it fall of the podium at the end of her exercise.
