Martha Gladys Chávez Cossío de Ocampo (born 12 January 1953) is a Peruvian Fujimorist politician and lawyer.

While Chávez backed Fujimori's own bid for the presidency, she decided to run a separate campaign after the National Jury of Elections banned Fujimori's name from the ballot on 10 January 2006, citing a political and congressional ban on his participation in Peruvian politics until 2011.

After a band of Fujimori sympathizers held a guard at gunpoint and heavily damaged the "Ojo Que Llora" ("Crying Eye"), a memorial to the victims of Peru's Internal War that included the names of victims of government death squads that operated under Fujimori such as Grupo Colina, Chávez said that she applauded the attack, and called the memorial "a garbage monument".

A month later, with 72 votes in favor, 35 against and 10 abstentions, in the plenary session of the Peruvian parliament, the Humalist majority, approved the suspension for 120 days of Chávez for her behavior during the inauguration ceremony of former president Ollanta Humala.

In the same way, it belongs to the Permanent Commission and to the Subcommittee of Constitutional Accusations; as well as the parliamentary leagues between Italy, Indonesia, Russia, China and Morocco.

In the 2020 snap parliamentary election, she returned to Congress after a brief 4-year absence on the Fuerza Popular list, representing Lima to complete the 2016–2021 term.

[6] One of her most controversial actions as congresswoman happened while the La Cantuta massacre case was making headlines in Peru.

Chávez responded by introducing a law that prohibited the judicial powers from calling low-level military officials to testify in court cases.

[7] The case was dismissed on the pretext that because the location of the bodies of the murdered students and professors was unknown, the courts had no way of knowing if they ever actually existed.

Chávez controversially characterized the judges on the Inter-American Court of Human Rights as leftist terrorist-sympathizers.
