The Tunjuelo or Tunjuelito River is a river on the Bogotá savanna and a left tributary of the Bogotá River. The river, with a length of 73 kilometres (45 mi) originates in the Sumapaz Páramo and flows northward through the Usme Synclinal to enter the Colombian capital Bogotá. There, the river is mostly canalised flowing westward into the Bogotá River. It is one of the three main rivers of the city, together with the Fucha and Juan Amarillo Rivers.
Etymology
The names Tunjuelo and Tunjuelito ("little Tunjuelo") are derived from the Cerro de los Tunjos, also Los Tunjos Lake, named after the tunjos, the religious votive figurines of the indigenous language of the Muisca, who inhabited the Bogotá savanna before the Spanish conquest.
Description

The river flows through the Usme Synclinal, where the type localities of various geological formations (among others the Marichuela Formation) are situated. The Tunjuelo River forms the border between the localities Usme and Ciudad Bolivar and between the namesake locality Tunjuelito and Ciudad Bolívar. The Tunjuelo River is highly contaminated.
