The Vichada River (Spanish: Río Vichada, Spanish pronunciation: [ˈri.o βiˈ tʃaða]) is a blackwater river in the country of Colombia, South America. It flows into the Orinoco River.
The westward course of the Vichada is offset by an impact structure, called the Vichada Structure. The structure is most likely the largest impact structure in South America.
