Presidential campaigns (2010–2026)
Fujimori ran for president in four consecutive general elections (2011, 2016, 2021 and 2026) and is the only candidate in modern Peruvian history to reach four consecutive presidential runoffs. She lost the first three by narrow margins before defeating Roberto Sánchez in 2026, becoming the first woman elected president of Peru and returning Fujimorism to power 25 years after her father's government collapsed. Her platforms consistently combined hardline security policies with defense of Peru's market-oriented economic model, while her handling of her father's legacy shifted from distance to open embrace.
In 2011, running for the newly founded Force 2011, she campaigned on her father's record against terrorism and economic instability while blaming its crimes chiefly on Vladimiro Montesinos and pledging not to pardon him. She placed second in the first round with 23.6% and lost the runoff to Ollanta Humala, 48.66% to 51.34%. The party, renamed Fuerza Popular in 2013, reorganized nationally ahead of a second bid.
In 2016 she made her most explicit break with her father's government, signing a "commitment of honor" against authoritarian practices, endorsing the Truth and Reconciliation Commission's findings and again promising no pardon. She won the first round decisively with about 40%, and Popular Force took 73 of 130 congressional seats, but her runoff lead collapsed amid money-laundering allegations against party secretary-general Joaquín Ramírez and renewed anti-Fujimorista mobilization; she lost to Pedro Pablo Kuczynski by roughly 41,000 votes (49.88% to 50.12%).
Fujimori subsequently led the congressional opposition with her party, controlling Congress for the next decade and utilizing what were described as obstructionist strategies to block policies aimed to prevent corruption while she attempted to govern Peru through the legislative body. Her party then engaged in constitutional hardball to remove multiple presidents from office between 2016 and 2026, removing power from the executive and placing it into Congress.
In October 2018, Fujimori was arrested on money-laundering charges over allegedly undeclared Odebrecht contributions to her campaigns, the Cocktails Case, spending intermittent periods in pretrial detention until May 2020. In 2021, reversing her 2016 pledge, she promised to pardon her father and campaigned on a "heavy hand" against crime. She advanced from the first round with 13.4%, her lowest share, and lost the runoff to Pedro Castillo by roughly 44,000 votes (49.87% to 50.13%). As Castillo's lead emerged she alleged fraud without presenting evidence and sought to annul some 200,000 predominantly rural votes; international observers found the election consistent with international standards, and commentators compared her challenge to Donald Trump's efforts to overturn the 2020 U.S. election.
According to Human Rights Watch, there were concerns for years that Fujimori's bloc in Congress was attempting to gain control of the Constitutional Court. In May 2022, 6 of 7 magistrates of the Constitutional Court were replaced in an opaque procedure by Congress, with the court subsequently supporting the opinions of the legislative body. After clashing with Congress throughout his presidency, President Castillo attempted to dissolve the legislative body on 7 December 2022, saying that it sought to create a "congressional dictatorship" with the help of the Constitutional Court, though both of the bodies mentioned rejected his position, ordered his removal from office and Castillo was arrested. On 4 December 2023, the Constitutional Court ordered the release of Keiko's father, Alberto, who died months later on 11 September 2024. The Constitutional Court annulled Fujimori's Cocktails Case trial in October 2025, and she announced her fourth candidacy days later; the case was dismissed in January 2026.
Campaigning under the slogan "Perú con orden" on a hardline security platform amid a national extortion and crime crisis, she won the first round with 17.18% and defeated Sánchez in the 7 June runoff by 49,641 votes out of more than 18 million cast, the outcome decided by overseas voters after a 22-day count. Sánchez refused to recognize the result, alleging irregularities in overseas ballots; electoral authorities and OAS and EU observer missions reported no significant irregularities.
