The Foce del Sele or "mouth of the River Sele" or Heraion at the mouth of the Sele is an archaeological site that contained an Ancient Greek sanctuary complex dedicated to the goddess Hera in Magna Grecia or southern Italy. It was originally located at the mouth of the Sele, about 9 kilometres north from the city of Paestum, then the Greek city of Poseidonia, which is famous for its three standing Greek temples. It is now in the modern commune of Capaccio-Paestum, some 50 miles south of Naples. The sanctuary is about 1.5 kilometres from the modern coast as a result of the deposition of alluvial sediment by the river.
