Luis Carlos Galán Sarmiento (29 September 1943 – 18 August 1989) was a Colombian liberal politician and journalist who ran for the Presidency of Colombia on two occasions, the first time for the political movement New Liberalism that he founded in 1979. The movement was an offspring of the mainstream Colombian Liberal Party, and with mediation of former Liberal president Julio César Turbay Ayala, Galán returned to the Liberal party in 1989 and sought the nomination for the 1990 presidential election, but was assassinated before the vote took place.

Galán declared himself an enemy of the drug cartels and the influence of the mafia in Colombian politics, in this case the main drug cartel being the Medellin Cartel led by Pablo Escobar and who unsuccessfully tried to become a member of the New Liberalism Movement in his bid to become a member of the Colombian House of Representatives. Galán denounced Pablo Escobar in a public rally, and supported the extradition treaty with the U.S, contrary to the wishes of the Colombian cartels that feared extradition to the U.S.

After receiving several death threats, on 18 August 1989, Galán was shot and killed by hitmen hired by the drug cartels of Pablo Escobar during a campaign rally in the town of Soacha, Cundinamarca. At the time, he was comfortably leading the polls with 60 percent favourable ratings for the forthcoming 1990 presidential election. While the investigation into his assassination remains unsolved, Galan's assassination was a crucial factor in the downfall of the Medellin Cartel a few years later.

Luis Carlos Galán Sarmiento was born on 29 September 1943 in the city of Charala, Santander. He had a happy childhood, with strong family bonds, affectionate and sometimes austere, as he had 12 siblings. His father moved with the whole family to Bogotá in 1949.^{[citation needed]}

In Bogotá, Galán attended middle school in the Colegio Americano in 1950. While a student there and only 8 years old, he joined a rally against Conservative president Laureano Gómez and intended to support the Liberal guerrillas. Two years later he was transferred to another school, the Colegio Antonio Nariño. When he was only a 14-year-old, Galán participated in the students protests of 1957 against the dictatorial regime of Gustavo Rojas, being arrested and spending the night in a jail despite his young age. In 1960 Galán graduated from high school with honors and began studies of law and economics in the Pontifical Xavierian University in Bogotá. While a student in 1963, Galán founded Vértice, a university focused magazine to express his Liberal tendencies in a university that was predominantly Conservative, which also became his first experience with journalism. He was able to meet prominent Colombian leaders like former Liberal president Carlos Lleras (who, delighted with Galán's work, decided to write articles for Vértice Magazine) and Colombia's main circulation newspaper El Tiempo owner and also former Liberal president of Colombia Eduardo Santos during an interview in which Santos was impressed by Galán's journalist qualities. Galán began working for the Colombian newspaper El Tiempo in 1965 after graduating from university the same year.

While working with El Tiempo, Galán turned himself into a well known journalist and columnist, an effort that earned him the director's assistant position and later the membership of the Executive Directorate in the newspaper with the support of Eduardo Santos and then director Roberto García Peña. He was also active with the Nueva Frontera weekly magazine founded by former president Carlos Lleras, which he directed in 1976 after arriving from Italy. As a journalist Galán wrote no less than 150 editorial articles, followed by another 150 during his time with the El Tiempo newspaper.

In 1977 Galán wrote an article in one of Nueva Frontera's editorials denouncing the existence of narcotics trafficking mafias and that they were influencing the social structure of Colombia. He also denounced the clientelist politics, moral values corruption and collective values loss, which was seen as a premonition for Colombia's future.

It was during an interview with the then recently elected president Misael Pastrana that he was surprised by the president in the middle of the interview who told Galán that he was going to be his Minister of Education.
