Agios Nikolaos is a village in Laconia, southern Greece, part of the municipality Monemvasia.

The original name of the village dating back in the 17th century was "Panagia" from a homonymous temple of Virgin Mary.

Most of the inhabitants trace their ancestry from the Western parts of Crete that was occupied by the Ottomans in 1669 resulting to a wide refugee influx in the Vatica area.

Moreover, people from the island of Kythera started populating the village from the early 19th century and onwards.

The village has a strong diaspora concentrated in Sydney, Australia and Pretoria, South Africa.
