María ( – ), better known as María la Grande or María Grande (English: María the Great), is the Christian name of a woman who served as the cacica of the southern Tehuelche people who lived in the Strait of Magellan and the Patagonian coast during the first half of the 19th century. Her direct domain was focused in the territory of the Bay of San Gregorio, in the present-day Chilean region of Magallanes, although she was called upon in other Patagonian regions when a conflictive situation required her judgment.
