Elections were held in the Argentine province of Chubut on 30 July 2023, to elect the Governor and Legislature of Chubut. These were part of the 2023 Argentine provincial elections. The province had abolished the simultaneous and mandatory open primaries (PASO), therefore parties held their own internal primaries to select their respective Gubernatorial candidates. In total, 5 candidates participated, and candidatures were submitted on 11 June.
The Governor and Vice-Governor of Chubut are elected on a joint ticket through first-past-the-post (FPTP) voting.
The Legislature of Chubut is elected every 4 years through party-list proportional representation in a single province-wide constituency with a majority bonus (16 seats reserved for the party obtaining the most votes, and 11 seats for all other parties).
