# 2011 Buenos Aires City elections

General elections were held in the City of Buenos Aires on 10 July 2011 to elect the Chief of Government (mayor), half of the City Legislature and all 150 members of the communal boards 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 incumbent Mauricio Macri, of the Republican Proposal (PRO) party, defeated Daniel Filmus of the Front for Victory (FPV) coalition to be re-elected as Chief of Government of Buenos Aires.
The City Legislature remained controlled by the governing PRO Alliance.
This was the first election in which members of the communal boards were elected, as the actual borders of the communes (comunas) had only been established in 2008 following the adoption of Law 1777, which created the commune subdivision system.

## Background

The 2007 elections in Buenos Aires resulted in the election of businessman and former Boca Juniors president Mauricio Macri in the second round against FPV candidate Daniel Filmus. Macri's party, Commitment to Change, and its alliance, Republican Proposal (PRO), also became the largest force in the City Legislature.
