San Andrés is an Olmec archaeological site in the present-day Mexican state of Tabasco. Located 5 km (3 miles) northeast of the Olmec ceremonial center of La Venta in the Grijalva river delta section of the Tabasco Coastal Plain, San Andrés is considered one of its elite satellite communities, with evidence of elite residences and other elite activities. Several important archaeological finds have been made at San Andrés, including the oldest evidence of the domesticated sunflower, insight into Olmec feasting rituals, didactic miniatures, and possible evidence of an Olmec writing system.
