Rodrigo Londoño Echeverri (born 22 January 1959), most known under the nom de guerre Timoleón Jiménez and the nickname Timochenko or Timochenco, is a Colombian politician, cardiologist and former commander-in-chief of the rebel group Revolutionary Armed Forces of Colombia (Spanish: Fuerzas Armadas Revolucionarias de Colombia, FARC), currently serving as the president of its political successor Commons (Spanish: Comunes) following the Colombian peace process.

Echeverri was born in 1959 shortly after the Cuban Revolution[1] to a poor peasant family in Calarcá,[2] near the birthplace of FARC-EP founder Manuel Marulanda.

[5] Colombian intelligence services had long believed that he had studied medicine in Cuba,[5] and the Soviet Union,[1] and then undergone military training in Yugoslavia,[1] but this has since been proven false.

[1][2] He explains, on his entry into the guerrilla: "Before I left, they gave me a talk in which they tried to discourage me, but I was determined: I admired the armed struggle and believed that it would only take a short time, as in Cuba".

[10] Between 28 and 31 August 2017, a month after being hospitalized for a cerebral embolism,[10] Echeverri led the founding congress of the Common Alternative Revolutionary Force (FARC) party at the Bogota Convention Centre with the participation of one thousand delegates.
