Carioca Arena 3, Olympic sports arena in Barra da Tijuca, Brazil.

Carioca Arena 3 is an indoor stadium in the Olympic Park at Barra Olímpica, in Rio de Janeiro's west zone. It hosted taekwondo and fencing at the 2016 Olympics and judo and wheelchair fencing at the 2016 Paralympics. In December 2022 it was renamed Isabel Salgado Olympic Educational Gymnasium and now serves 5,000 students.

The venue was built for the 2016 Olympic Games serving taekwondo and fencing competitions. It later hosted judo and wheelchair fencing during the Paralympic Games that followed.

In December 2022 the venue was renamed Ginásio Educacional Olímpico Isabel Salgado, after the Rio-born volleyball player Isabel Salgado, who died that year and had won Olympic medals in 1984 and 1988. The name ties the former Olympic arena to a Brazilian athlete rather than to a competition.

The arena sits in the Olympic Park in Barra Olímpica, in Rio's west zone. Since December 2022 it has been refurbished as a school, the Ginásio Educacional Olímpico Isabel Salgado, serving 5,000 students, so access follows school use rather than event crowds. The planned sports school was to include science and media laboratories and two multi-use rooms.

During the COVID-19 pandemic, the arena was quickly transformed into a vaccination center serving mass immunization efforts. It later resumed its role and now educates around 5,000 students through athletic training programs.
