Adán Chávez Frías (born April 11, 1952) is a Venezuelan politician who was Governor of Barinas state from 2008 to 2016. Previously he was Ambassador to Cuba and then Minister of Education from 2007 to 2008.

Adán studied at the University of the Andes, in Mérida where he was involved with pro-guerrilla groups prior to the election of his brother Hugo into the presidency.^[1] Through Adán, Hugo met with guerrilla fighters Douglas Bravo and William Izarra.^[2]

After Hugo was elected as president, he appointed Adán as Ambassador to Cuba. In August 2006, Adán became Presidential Secretary, replacing Delcy Rodríguez, who reportedly disagreed with Hugo Chávez during his international tour. The Charlotte Observer reported that the author of several books on Chávez, Alberto Garrido, argued: "A much more hard-line phase [of Chávez rule] is beginning and Chávez needs a reliable and radical team around him." In January 2007, Hugo appointed Adán as Minister of Education.^{[citation needed]} In 2008, he was elected as Governor of Barinas as the United Socialist Party of Venezuela (PSUV) candidate, replacing his father Hugo de los Reyes Chávez.^[3]

Chávez has been critical of the United States government, stating to PSUV members in 2018 that "we have an enemy, the American empire is our fundamental enemy, nobody can get lost in the forest of other considerations".^[4]

He is the eldest brother of Hugo Chávez (1954–2013), who was President of Venezuela from 1999 to 2013, the mayor of Sabaneta, Barinas, Anibal José Chávez Frías (1956–2016) and his successor in the gubernatorial position, Argenis Chávez (born 1958), who served for one term from 2016 to 2021.
