Maribel Parra de Mestre (born 24 August 1965) is a Venezuelan naval officer and oil company executive.
She graduated 11th in her class from the Military Academy of the Bolivarian Navy and her naval career included experience in the field of logistics, as an aide to the First Lady of Venezuela and deputy commander of cadets at the navy academy.
In 2011 she became the first woman from Zulia to reach the rank of rear admiral and in 2014 was the first Venezuelan woman to be promoted to the rank of vice admiral.
A supporter of former president Hugo Chávez, she was appointed by Chavez's successor Nicolás Maduro as executive vice president of the country's state-owned oil company PDVSA in 2017.
This was interpreted by some as a takeover of the oil sector by the military.
