Hugo Rafael Chávez Frías (Spanish pronunciation: [ˈuɣo rafaˈel ˈtʃaβes ˈfɾi.as]; born 28 July 1954) is the current President of Venezuela, having held that position since 1999.

He was formerly the leader of the Fifth Republic Movement political party from its foundation in 1997 until 2007, when he became the leader of the United Socialist Party of Venezuela (PSUV). Following his own political ideology ofBolivarianism and "Socialism for the 21st Century", he has focused on implementing socialist reforms in the country as a part of a social project known as the Bolivarian Revolution, which has seen the implementation of a new constitution, participatory democratic councils, the nationalization of several key industries, increased government funding of health care and education, and significant reductions in poverty, according to government figures.

Born into a working-class family in Sabaneta, Barinas, Chávez became a career military officer, and after becoming dissatisfied with the Venezuelan political system, he founded the secretive Revolutionary Bolivarian Movement-200 (MBR-200) in the early 1980s to work towards overthrowing it. Chávez led the MBR-200 in an unsuccessful coup d'état against the Democratic Action government of PresidentCarlos Andrés Pérez in 1992, for which he was imprisoned. Getting out of prison after two years, he founded a social democratic political party, the Fifth Republic Movement, and was elected president of Venezuela in 1998. He subsequently introduced a new constitution which increased rights for marginalized groups and altered the structure of Venezuelan government, and was re-elected in 2000. During his second presidential term, he introduced a system of Bolivarian Missions, Communal Councils and worker-managed cooperatives, as well as a program of land reform, whilst also nationalizing various key industries. On 7 October 2012, Chávez won his country's presidential election for a fourth time, defeating Henrique Capriles, and was elected for another six-year term.

Chávez describes his policies to be anti-imperialist, and he was a vocal critic of neoliberalism and laissez-faire capitalism. More generally, Chávez has been a prominent adversary of the United States' foreign policy. Allying himself strongly with the Communist governments of Fidel and then Raúl Castro in Cuba and the Socialist governments of Evo Morales in Bolivia, Rafael Correa in Ecuador and Daniel Ortega in Nicaragua, his presidency was seen as a part of the socialist "pink tide" sweeping Latin America. He has supported Latin American and Caribbean cooperation and was instrumental in setting up the pan-regional Union of South American Nations, the Bolivarian Alliance for the Americas, the Bank of the South, and the regional television network TeleSur. Chávez was a highly controversial and divisive figure both at home and abroad.

On 30 June 2011, Chávez stated that he was recovering from a June 10 operation to remove an abscessed tumor with cancerous cells. He required a second operation in December 2012. Chávez was to have been sworn in on January 10, 2013, but the National Assembly of Venezuela agreed to postpone the inauguration to allow him time to recuperate and return from a third medical treatment trip to Cuba. On 1 March 2013, Venezuelan vice president Nicolas Maduro reported that Chávez was in "good spirits", although fighting for his life.
