2007 Buenos Aires City elections

General elections were held in the City of Buenos Aires on 3 June 2007 to elect the Chief of Government (mayor) and half of the City Legislature to four-year terms. As no mayoral candidate won a majority in the first round, a runoff was held on 31 July 2011, in which Mauricio Macri, of the Commitment to Change (CpC) party, defeated Daniel Filmus of the Front for Victory (FPV) coalition to be elected as Chief of Government of Buenos Aires.

Incumbent Jorge Telerman, who had assumed office just over a year prior to the election following the impeachment of Aníbal Ibarra over repercussions from the 2004 Cromañón nightclub fire, sought re-election but was defeated in the first round.

The 2003 elections in Buenos Aires resulted in the re-election of progressive former prosecutor and mayor Aníbal Ibarra, of the Broad Front, in the run-off against centre-right businessman and former Boca Juniors president Mauricio Macri, of Commitment to Change (CpC).

Just a year later, however, the Cromañón nightclub fire led to Ibarra's suspension from office in 2005 and eventual impeachment in 2006, amid accusations of corruption and negligence. Ibarra was replaced by his deputy, Jorge Telerman.

As the existing political alliances had crumbled in the aftermath of Cromañón, Telerman sought re-election on the Civic Coalition ticket, with former mayor Enrique Olivera as running mate, while Macri and his CpC party, now part of the Republican Proposal alliance, geared up for a second attempt at the mayorship. The peronist Front for Victory nominated sociologist and national education minister Daniel Filmus, deputised by labour leader Carlos Heller.
