The Usme Formation (Spanish: Formación Usme, Tsu, Teu) is a geological formation of the Bogotá savanna, Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes.

The formation consists of a lower part with predominantly shales with intercalated sandstone beds and an upper sequence with sandstones and conglomerates.

The Usme Formation dates to the Neogene and Paleogene periods; Late Eocene to Early Oligocene epochs, and has a maximum thickness of 300 metres (980 ft).

The formation was defined by Hubach in 1957 and named after the locality of Usme, Bogotá.

[2] The age has been estimated, based on palynological data, to be Late Eocene to Early Oligocene.
