The petrified forest of Lesbos is a petrified forest on Lesbos in Greece.
It has been designated as a protected natural monument. The petrified forest of Lesbos was formed from the fossilized remains of plants, which can be found in many localities on the western part of Lesbos Island. The area enclosed by the villages of Eressos, Antissa and Sigri is very dense in fossilized tree trunks and forms the Petrified Forest of Lesbos, which is managed by the Natural History Museum of the Lesvos Petrified Forest. Isolated plant fossils can be found in many other parts of the island, including the villages of Molyvos, Polichnitos, Plomari and Akrasi.
Petrified forest of Lesbos is a major geosite of "Lesvos Geopark".
The Petrified forest of Lesbos, as of Spring 2014, was proposed for UNESCO's Tentative List of World Heritage Sites.
