Pisa (Ancient Greek: Πῖσα) is a modern village situated 2.15 kilometres (1.34 mi) to the east of Olympia, Greece. Currently it is not politically independent but is a neighborhood of the village of Archea Olympia, the capital of the Municipality of Ancient Olympia, of which it is a municipal unit, Ancient Olympia, since 2011. Municipality (deme), municipal unit, village, and ancient site, all telescope at the same location under the same Greek name, archaia Olympia, although different English translations provide some diversity at the different levels. They are all in the regional unit of Elis, located on the northwest side of the geographic (not political) feature of the Peloponnesus

Modern Pisa is the putative location of ancient Pisa. Greek history tells of a contention between Olympia, Pisa, and Elis, a village of ancient Elis, for supremacy of the region and management of the sacred precinct. The existence of an ancient district called Pisatis (ἡ Πισᾶτις), which included 8 villages over half of modern Elis, is indicated by many ancient authors. Such a political unit is certain for the 4th century BC.^[1] The tradition of an earlier unit is not an unreasonable one. Eventually Olympia was victorious in the contention and Pisa became part of Olympia rather than vice versa.
