The 2026 election cycle in Mato Grosso do Sul has led to several legislative transitions within municipal chambers. In Campo Grande, André Salineiro (PL) was elected as a state deputy, with Cassy Monteiro (PL) designated to fill the vacancy in 2027. In Dourados, Isa Marcondes (Republicanos) was elected to the Chamber of Deputies, leaving her seat to Fábio Luís. Similarly, in Rio Brilhante, Daverson Matos (PL) was elected as a state deputy, to be replaced by Lucas Ferreira (PL).
