Iguazu Falls, Iguassu Falls, or Iguaçu Falls are waterfalls of the Iguazu River located on the border of the Brazilian state of Paraná and the Argentine province of Misiones. The falls divide the river into the upper and lower Iguazu. Iguazu Falls was short-listed as a candidate to be one of the New7Wonders of Nature by the New Seven Wonders of the World Foundation. As of February 2009 it was ranking fifth in Group F, the category for lake, rivers, and waterfalls.

The waterfall system consists of 275 falls along 2.7 kilometers (1.67 miles) of the Iguazu River. Some of the individual falls are up to 82 meters (269 ft) in height, though the majority are about 64 metres (210 ft). The Devil's Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese), a U-shaped, 82-meter-high, 150-meter-wide and 700-meter-long (490 by 2300 feet) cataract, is the most impressive of all, and marks the border between Argentina and Brazil. Two thirds of the falls are within Argentine territory. [1] About 900 meters of the 2.7-kilometer length does not have water flowing over it. The edge of the basalt cap recedes only 3 mm per year. The water of the lower Iguazu collects in a canyon that drains into the Paraná River at Argentina, shortly downstream from the Itaipu dam.
