El Calafate, also called Calafate, is a city in the Argentine province of Santa Cruz, in Patagonia. It is located on the southern border of Lago Argentino, in the southwest part of the province. The name of the city is also the name of a small bush, with yellow flowers and dark-blue berries, that is very commonly seen in the region—the calafate. The word comes from the word calafate, which is Spanish for 'caulk'.
