Franklyn Allen "Tex" Harris (May 13, 1938 – February 23, 2020) was an American diplomat best known for his work as a political officer in the United States embassy to Argentina between 1977 and 1979, where he tracked the victims of "enforced disappearances" during the Dirty War of the Argentinian military dictatorship.

Despite a lack of official support and even obstruction, his work proved consequential in exposing the junta's abuses and became a major influence on American foreign policy towards Argentina and human rights.

According to Harris, his father Murray (originally Shlimka Simselowitz) was a Russian Jew who fled from persecution there to Germany and later the United States.

[3] Harris was assigned to Argentina in 1977 as the embassy's human rights officer in the midst of the "National Reorganization Process", the military dictatorship that ruled the country between 1976 and 1983.

[9][11] The Argentinian government attempted to intimidate those who went in by using phone taps and filming everyone who went in and out of the embassy; nevertheless, Harris' records have been described as the most complete, with around 13,500 individual documents.

[12][13] The reports had immediate effect; Patricia M. Derian, at the time the Assistant Secretary of State for Human Rights and Humanitarian Affairs, used the data Harris and Vollenweider collected to put pressure on officials in both Washington and Buenos Aires, ultimately leading to Congress passing a law prohibiting military aid and arms sales to the country until the human rights situation improved.

[6] He was stationed in South Africa during the country's transition from apartheid and led anti-HIV efforts as the deputy director of the Office of Southern African Affairs.
