The Nahua are an Indigenous group of Mesoamerican people inhabiting the western and central areas of present-day El Salvador. They speak the Nawat language, which belongs to the Nahuan language branch of the Uto-Aztecan language family. There are very few speakers of the language left, which is a reason for the current efforts being made to revitalize it.

The Nahuas are a group of the Indigenous people of Mexico, El Salvador, Guatemala, Honduras, Nicaragua, and Costa Rica. They comprise the largest indigenous group in Mexico and El Salvador. They are a Mesoamerican ethnicity. The Mexica (Aztecs) are of Nahua ethnicity, as are their historical enemies, the Tlaxcallans (Tlaxcaltecs), and the Toltecs which predated both groups are often thought to have been as well. However, in the pre-Columbian period Nahuas were subdivided into many groups that did not necessarily share a common identity.
