2026 Rio de Janeiro gubernatorial special election
Indirect Election for Interim Governor of the State of Rio de Janeiro

The 2026 Rio de Janeiro gubernatorial special election was triggered due to the definitive vacancy of the offices of Governor and Vice-Governor of Rio de Janeiro, after the resignation of governor Cláudio Castro on 23 March 2026.
The Supreme Federal Court began deciding on 8 April whether the election will be indirect, in which only members of the Legislative Assembly of Rio de Janeiro (Alerj) vote, or direct, with all voters in the state participating. Following the Superior Electoral Court's (TSE) ruling clarifying the legal status of Cláudio Castro's resignation, the trial was scheduled to resume on 19 August 2026.
Background
The succession crisis in Rio de Janeiro reached a climax with the resignation of Cláudio Castro in March 2026. With the absence of a Vice-Governor in office (as it was already vacant), the state faced a "double vacancy", as the president of the Legislative Assembly (second in the line of succession) had been suspended since December 2025 by a ruling of the Supreme Federal Court. According to the line of succession, the President of the Court of Justice of Rio de Janeiro (TJ-RJ), Justice Ricardo Couto de Castro, took office as Acting Governor until the indirect election and the inauguration of a new Governor.
Resignation of Thiago Pampolha
The succession crisis in Rio de Janeiro began with the resignation of Thiago Pampolha (MDB), who had been elected Vice-Governor in 2022 on Cláudio Castro's ticket, in order to assume a position as a Justice (Conselheiro) of the State Court of Accounts (TCE-RJ). The vacancy arose following the retirement of José Maurício de Lima Nolasco, who had held the position since 1998 after being appointed by then-Governor Marcello Alencar.
Pampolha's appointment resulted from a political agreement between Castro and the then-President of the Legislative Assembly of Rio de Janeiro, Rodrigo Bacellar (UNIÃO). At the time, Bacellar was positioning himself as a potential candidate for governor and, as first in the line of succession in the absence of a Vice-Governor, stood to benefit politically from increased visibility.
