Cerro Marahuaca, also spelled Marahuaka (Ye'kuana: Madawaka[2]), is a tepui in Amazonas state, Venezuela.

It has an elevation of 2,832 metres (9,291 ft) above sea level[1][3] and is the second-highest mountain of the entire Guayana Shield (after the Cerro de la Neblina complex).

A massive ridge known as Cerro Petaca rises to at least 2,700 metres (8,900 ft) just west of these two plateaus.

[4] In 1973, the Italian expeditioner Walter Bonatti attempted to climb Cerro Marahuaca without success.

[4] Several frog species are only known from the summit of Cerro Marahuaca, including Pristimantis marahuaka,[5] Metaphryniscus sosai,[6] and Myersiohyla inparquesi.
