Carmen Hertz Cádiz (born 19 June 1945) is a Chilean Communist Party politician and lawyer who participated in various institutions for the protection of human rights that arose as a result of the systematic violations committed during the dictatorship headed by Augusto Pinochet from 1973 to 1990.

During the Popular Unity alliance, Hertz was a legal secretary of the council of the Agrarian Reform Corporation [es] (1970–1973),[2] which was chaired by the Minister of Agriculture, Jacques Chonchol.

When her friend Carlos Berger – a lawyer and a communist journalist who had gone to Moscow for a year, and with whom she had maintained an active correspondence – returned to Chile in 1971, they immediately began a romantic relationship.

The family left for Chuquicamata in August, and there, Berger took over as director of Radio El Loa and Hertz began working in the mining company's legal department.

[4] The death of her husband led Hertz to participate in various organizations dedicated to the defense of human rights, including the Vicariate of Solidarity, and later in the National Corporation for Reparation and Reconciliation [es].

[2] The story of her search for justice for Berger's murder was brought to the small screen by Andrés Wood in the miniseries Ecos del desierto [es].

[5] Their son Germán became a filmmaker and journalist, and directed the documentary Mi vida con Carlos about his father's killing, which was nominated for four Goya Awards in 2010.

She was successful, however, in the 2017 election, in which she won a seat for District 8 (Cerrillos, Colina, Estación Central, Lampa, Maipú, Tiltil, Pudahuel, and Quilicura).
