Article 421 of Libya's Penal Code prohibits "indecent acts and articles" with imprisonment of up to one year or a fine of up to 50 pounds. Law No. 11, which Libya adopted in 2016, forbids actions “contrary to public morals and the provisions of Islamic law”. These laws are commonly used to detain suspected LGBTQ+ individuals.

Articles 407 and 408 of the Penal Code of 1953 criminalize homosexuality. Article 407 criminalizes “illicit sexual intercourse” with up to 5 years in prison, and Article 408 criminalizes anyone who ‘commits an indecent act with a partner with his consent’ with imprisonment.

In 1953, Santiago del Estero added Articles 77 and 78 to its Code of Misdemeanours. Article 77 criminalises anyone who "offends public decency with clumsy acts or words" with 10 days in prison. Article 78 says that people who are "publicly exhibited with clothes of another sex" except during carnivals or other parties where doing so is permitted are included as offenders of the previous article, criminalising the expression of transgender people. Even during carnivals and parties allowing it, the choice of clothing must not be "indecorous". The laws were repealed in 2008.

In 1953, Catamarca passed Law 1573, the Code of Misdemeanours, which included Article 101 which punished "dressing or impersonating a person of the opposing sex" with 20 days imprisonment or a fine. This was repealed in 2005.

Since 1953, various provinces have passed discriminatory laws targeting LGBTIQ+ people and their expressions, starting with Catamarca. Laws would begin to be repealed in the 1990s and continued into the 21st century with Formosa being the last province to repeal such laws in 2012. During the military dictatorship from 1976 to 1983, LGBTIQ+ people faced extreme persecution with the junta harassing people for their sexual orientation or gender identity.
