Lake Nicaragua or Cocibolca or Granada (Spanish: Lago de Nicaragua, Lago Cocibolca, Mar Dulce, Gran Lago, Gran Lago Dulce, or Lago de Granada) is a massive freshwater lake in Nicaragua of tectonic origin. With an area of 8264 km², it is the third largest lake in Latin America, the 21st largest lake in the world and only slightly smaller than Lake Titicaca. With an elevation of 32 m (105 ft) above sea level, the lake reaches a depth of 26 m (84 ft). It is intermittently joined by the Tipitapa River to Lake Managua.
The lake is connected to the Caribbean Sea by the San Juan River, historically making the lakeside city of Granada, Nicaragua an Atlantic port although it is closer to the Pacific. The lake has a history of Caribbean pirates. Despite draining into the Caribbean Sea, the Pacific Ocean is near enough to be seen from the mountains of Ometepe.
