Luis Miguel Gerónimo Barbosa Huerta (30 September 1959 – 13 December 2022) was a Mexican politician affiliated with Morena who served as Governor of Puebla from 2019 until his death in 2022.

[3] Two years later, he left his law firm and became a federal deputy in the LVIII Legislature, with committee assignments including Public Safety, Navy, and Parliamentary Practices.

[11] Barbosa supporters challenged the election results in court, and in early December 2018, the Superior Chamber of the Federal Electoral Tribunal affirmed Alonso's victory.

[15] A similar Juntos Haremos Historia coalition, with the Ecologist Green Party of Mexico (PVEM) replacing the liquidated Social Encounter, ran Barbosa as its candidate and received 44.6 percent of the vote.

[20] The COVID-19 pandemic in Mexico dominated Barbosa's time in office; on 24 March 2020, he claimed that only the wealthy were at risk of contracting the disease and that the poor—including himself—were immune.

[33] Rumors had circulated of a medical event involving the governor since the preceding day,[29] and at his last public appearance, he admitted that he was suffering from pain in his arm.

[32] Unlike after Martha Érika Alonso's death, when a special election was called, the state legislature would appoint a successor to Barbosa because the vacancy occurred in the final four years of the gubernatorial term.

[15] This occurred early on 15 December with the appointment of Sergio Salomón Céspedes of Tepeaca, who had been the leader of the Morena deputies in Puebla's state legislature.
