Yamandú Ramón Antonio Orsi Martínez[a] (born 13 June 1967) is a Uruguayan politician and teacher who is the president-elect of Uruguay after winning the 2024 general election.

[5] He began to be a political militant during his adolescence, being part of the Vertiente Artiguista until 1990, when he joined the Movement of Popular Participation (MPP) that had been founded the previous year.

He is the second child, with an older sister, María del Luján, and the only son of Pablo "Bebe" Orsi (1933–2018), a rural laborer, and Carmen "Beba" Martínez (died 2023), a seamstress.

[7][8] Orsi is of paternal Italian descent, tracing his heritage to Osiglia, a municipality situated in the province of Savona, in the Liguria region of Italy.

[10] Following his presidential election victory, Paola Scarzella, the current mayor of Osiglia, congratulated Orsi and expressed her excitement upon learning his ancestral connection, "It is a great honor that someone with roots in our community has reached such a prominent position."

[13][14] Raised in a rural area between the towns of Santa Rosa and San Antonio, the family struggled financially during Orsi's adolescence years and, for a time, lived in a house without electricity.

[21] In 2004, while still working as a history teacher in Maldonado, he ran unsuccessfully for the Chamber of Representatives as the fourth candidate on the electoral list of the Movement of Popular Participation in the Canelones Department.

[27] In October 2019, facing the second round of the general election, Orsi was appointed campaign manager for Broad Front nominee Daniel Martínez Villamil.

[34] On 9 December 2023, during the Broad Front Congress, Orsi's candidacy was made official, as well as that of Carolina Cosse, Mario Bergara, and Andrés Lima.

[39] The following day, outgoing president Luis Lacalle Pou chaired a meeting with the nation's cabinet to plan out the presidential transition for Orsi.

[40] Later that day, Orsi traveled with key advisors to Brasília for a meeting with Brazilian President Luiz Inácio Lula da Silva to discuss infrastructure projects.

At the summit, the final text of the MERCOSUR-European Union free trade agreement was concluded after nearly 25 years of negotiations, during which, Orsi held bilateral meetings with regional leaders, including Gustavo Petro, Luis Arce, and Santiago Peña.
