General elections were held in Peru on 10 April 2011 to elect the President, the Vice Presidents, 130 members of Congress and five members of the Andean Parliament. As no presidential candidate received a majority in the first round, a second round was held on 5 June to determine the successor of outgoing president Alan García. Former army officer Ollanta Humala narrowly defeated Keiko Fujimori, daughter of imprisoned former President Alberto Fujimori. Humala was sworn in as the 94th President of Peru on 28 July.

Óscar Luis Castañeda Lossio was a Peruvian politician who was the Mayor of Lima, the capital city of Peru, from 2003 to 2010. He became Mayor of Lima again in 2015, after being elected for a third nonconsecutive term with 51% of the popular vote, for a term that lasted until 31 December 2018. He ran for President of Peru twice, in the 2000 elections placing fifth, prior to his mayoral campaign in 2002, and in the 2011 elections, placing fifth again with 9.8% of the vote.
