The National Solidarity Alliance was an electoral alliance in Peru formed for the 2011 general election, dominated by the eponymous National Solidarity Party and led by presidential candidate Luis Castañeda.

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.
