El Opeño is a Mesoamerican archaeological site located in the municipality of Jacona, in the Michoacán state, México. It is home to a prehispanic site, mainly known from the ceramic material found in the funerary complexes of the site, which have been dated to the Late Preclassic period.
The importance of this site in mesoamerican archaeology is due to its antiquity and the ample diffusion of its style, contemporary to other native culture developments such as the Capacha culture and earlier of the Chupicuaro. El Opeño tombs are the oldest in Mesoamerica. Have been dated to around 1600 BCE, hence they predate de Olmec culture development, with main centers in the Gulf of Mexico coast and flourished some centuries later.
