Humberto Calderón Berti (born 21 October 1941 in Boconó, Venezuela^[1]) is a Venezuelan geologist, petroleum engineer, diplomat, politician and author, named in 2019 as ambassador to Colombia by disputed interim Venezuelan president Juan Guaidó during the 2019 Venezuelan presidential crisis,^[2][3] and welcomed by Carlos Holmes Trujillo, Colombia's foreign minister.^[2]

In 2003, he and other former PDVSA petroleum executives founded the Colombian company, Vetra Energia, S.L.^[4] He solicited and was granted Spanish citizenship, where he has family and cultural ties, in 2018 because of persecution due to his membership in Venezuela's Social Christian political party (Copei).^[5]
