The Pasión River (Spanish: Río de la Pasión, Spanish pronunciation: [ˈri.o ðe la paˈsjon]) is a river located in the northern lowlands region of Guatemala. The river is fed by a number of upstream tributaries whose sources lie in the hills of Alta Verapaz. These flow in a general northerly direction to form the Pasión, which then tends westwards to meet up with the Salinas River at (16°28′52″N90°32′39″W). At this confluence the greater Usumacinta River is formed, which runs northward to its eventual outlet in the Gulf of Mexico.
