Ano Diakopto is a mountain village located in the regional unit of Achaea, within the Peloponnese region of Greece. It is part of the municipal unit of Diakopto, which is a subdivision of the municipality of Aigialeia.
The village is situated in the northern Peloponnese, positioned at an elevated location on the slopes overlooking the coastal plains and the Gulf of Corinth. The name "Ano," meaning "Upper" in Greek, distinguishes the settlement from the coastal town of Diakopto located below. Historically, the village was known as Pera Machala (Greek: Πέρα Μαχαλά) until it was officially renamed to reflect its geographic relationship with the coastal settlement.
Administratively, Ano Diakopto functioned as an independent community until the implementation of the 1997 Kapodistrias reform, which integrated it into the municipality of Diakopto. Following the 2011 Kallikratis Plan, it became part of the larger Aigialeia municipality. According to the 2011 Greek national census, the village of Ano Diakopto had a population of approximately 304 inhabitants, while the broader local community (including the settlement of Pouliou) totaled 317.
The local economy is primarily based on agriculture, with the surrounding landscape characterized by olive groves and fruit orchards. The village is situated near the Vouraikos Gorge, a protected area known for its biodiversity and the Diakopto–Kalavryta rack railway, although the primary station for the railway is located in the coastal town of Diakopto. Geographic and administrative records confirm the village as an established settlement within the Hellenic Republic's regional structure.
