Osvaldo Francisco Jaldo (Trancas, April 19, 1958) is an Argentine public accountant and politician, a former member of Union por la Patria.

He received his degree as a national public accountant from the Universidad del Norte Santo Tomás de Aquino.

[2][3] In September 2021, following the appointment of Governor Manzur as head of the Cabinet of Ministers, summoned by the President of the Nation Alberto Fernández, Jaldo was placed in charge of the provincial Executive Branch.

[4] In 2023 he was elected governor of Tucumán accompanied by Miguel Acevedo as a candidate for vice-governor who ran for the banning of Juan Manzur, obtaining the 54.96% of the votes against Roberto Sánchez of Together for Change.

In the PASO Elections of 2021 he generated controversy by breaking the unity of the Justicialista Party of Tucumán by presenting himself as a candidate for Deputy, generating an internal when facing the list of candidates of the governor Juan Manzur, in addition to a series of statements against the driver of the executive government of the province.

In September 2021, Manzur was appointed Chief of Ministers, so Jaldo assumed the Interim governorship, calming the internal situation.

[8] After this, the governor argued that "the national government acceded to the requests of Tucumán and the different sectors of production" and declared that they were not being pressured by anyone and acted in total freedom.
