2023 Campeonato Brasileiro de Futebol Feminino Série A3

The 2023 Campeonato Brasileiro de Futebol Feminino Série A3 (officially the Brasileirão Feminino Binance A3 2023 for sponsorship reasons) was the second season of the Campeonato Brasileiro de Futebol Feminino Série A3, the third level of women's football in Brazil. The tournament was organized by CBF. It started on 21 April and ended on 25 June 2023.

Thirty-two teams competed in the tournament. Twenty-eight qualified from their state leagues and four relegated from the 2022 Série A2 (Aliança/Goiás, CEFAMA, Iranduba and Vasco da Gama). As the Federação Amazonense de Futebol suspended the Iranduba men's team for two years due to their possible involvement in match-fixing, the Iranduba women's team was expelled from the Série A3. They were replaced by VF4 (2022 Série A3 fifth place).

The four semi-finalists, Juventude, Mixto, Remo and VF4, were promoted to the 2024 Campeonato Brasileiro de Futebol Feminino Série A2.

Mixto defeated Remo 4–0, on aggregate, in the finals to win their first title.

Format
The competition was a single-elimination tournament with each round contested a home-and-away two-legged basis. The first rounds were organized regionally. In the round of 32, the highest-ranked team in the 2023 Women's Club Ranking hosted the second leg. If the teams had the same rank the highest-ranked-federation team in the 2023 Women's State Ranking would host the second leg.

Starting from the round of 16, the teams were seeded according to their performance in the tournament. The teams were ranked according to overall points. If tied on overall points, the following criteria would be used to determine the ranking: 1. Overall wins; 2. Overall goal difference; 3. Overall goals scored; 4. Fewest red cards in the tournament; 5. Fewest yellow cards in the tournament; 6. Draw in the headquarters of the Brazilian Football Confederation (Regulations Article 15).

If tied on aggregate, the away goals rule would not be used, extra time would not be played, and the penalty shoot-out would be used to determine the winners (Regulations Article 14).

The four semi-finalists were promoted to the 2024 Campeonato Brasileiro de Futebol Feminino Série A2.
