Lucas Rincón Romero (born 1 February 1950) is a Venezuelan military officer.

Lucas Rincón was the highest-ranking Venezuelan military officer at the time of the 2002 coup d'état attempt against Venezuelan President Hugo Chávez.^[2] He announced in a television broadcast that Chávez had resigned, "se le solicitó al señor presidente la renuncia de su cargo, la cual aceptó" (the president was asked to resign his post, which he accepted).^[3] He had been one of Chavez's most loyal military officers.^[4]

Chávez was returned to power within three days and there has since been debate as to whether the resignation was genuine.^[5] Chávez said in a BBC interview in October 2005 that media reports that announced that he had renounced his position were false.^[6]
