The incumbent governor at the time, Reinaldo Azambuja, wasn't allowed to run for reelection for a third consecutive time due to term limits established by the Federal Constitution of Brazil (art. 14, paragraph 5).

The governor and the vice governor are both elected for a four-year term starting 1 January 2023 and with the approval of Constitutional Amendment nº 111, their terms will end on 6 January 2027.

For the Federal Senate election, the seat occupied by the incumbent Simone Tebet (MDB) was at dispute.

Tereza Cristina, the former Minister of Agriculture of Brazil under the Presidency of Jair Bolsonaro, was elected to replace Tebet as a senator for an eight-year term (2023–2031).
