General elections were held in the City of Buenos Aires on 27 October 2019, coinciding with the general election being held nationwide. The Chief of Government (mayor), half of the City Legislature and all 150 members of the communal boards were elected to four-year terms.

In the mayoral election, incumbent Horacio Rodríguez Larreta of the PRO party was re-elected for a second term with a record 55.90% of the vote. This was the first election since the adoption of the city's 1996 Constitution, which granted autonomy to the city and allowed it to vote for its own Chief of Government, in which a candidate won in the first round of voting. ^[1]

Background

The 2015 elections in Buenos Aires resulted in election of Horacio Rodríguez Larreta, former cabinet chief to Mauricio Macri and a leading figure within Republican Proposal (PRO) and its Juntos por el Cambio alliance (JxC). JxC also remained the largest force in the City Legislature. ^[2]

Ahead of the 2019 election, the different parties of the Juntos por el Cambio coalition agreed to avoid a primary and unanimously backed the candidacy for re-election of Rodríguez Larreta. ^[3] For their part, the newly formed opposition Frente de Todos coalition (made up of the Justicialist Party, the Renewal Front and other peronist and progressive parties) nominated businessman and San Lorenzo de Almagro president Matías Lammens. ^{[4] [5]}
