San Vicente (Spanish pronunciation: [sam biˈsente]) is a department of El Salvador in the center of the country.

During the Salvadoran Civil War, the region was considered a stronghold for the rebel Farabundo Martí National Liberation Front.

In August 1982, the Salvadoran Army began a campaign in the area, moving in with ground troops after several days of bombing.

On August 21–22, the Atlácatl Battalion surprised a group of hundreds of refugees at El Calabozo beside the Amatitán river, opening fire at close range.

This was a place of adoration to the Aztec gods, and the found structures demonstrates the type of hierarchical organization their tribes had.
