Elafonisos(Greek: Ελαφόνησος) is a small Greek island between the Peloponnese (Greek: Πελοπόνησος) and Kythira (Greek: Κύθηρα). It lies off the coast of Cape Malea (Greek: Ακρ. Μαλέας) and is located in the municipality of the Vatika (Greek: Βάτικα). The area of the island is 19 km². In modern times, Elafonisos was first inhabited before 1850.
The population which is circa 400 to 450 citizens during the winter, increases during the summer months due to the inflow of Elafonisiotes habiting the urban centers. The tourist High season is during the months of July and August reaching 5,000 visitors and 1,600 cars per day. In May, June and September the island , becomes personal.
Many people visit the island for its light coloured, sandy beaches on the southern tip of the island. There are three main beaches on the island, that of Simos (Greek: Σίμος), Saraceniko (Greek: Σαρακίνικο) and Panagias (Greek: Παναγίας), which are filled with golden-green waters. Just across the island 570 m to the mainland there is the Punta (Greek: Πούντα) beach.
On the nearby mainland, approximately 6.5 km (3.7 nmi) east is Neapoli (Greek: Νεάπολη) of the municipality of Vatika. About 8.5 km (4.5 nmi) south is Cape Frangos (Greek: Φράγκο) in the island of Kythira.
3 km² of the community's land includes the mainland which is consisted of mainly Punta. Today, Elafonisos is the only inhabited island of the Peloponnese.
The island is also known as Elafonisi/Lafonisi (Λαφονήσι) just like Elafonisi in Northwestern Crete. The name of Elafonisos probably has a historical origin, and means the "island of deers".
The main church in the village is of Agios Spyridon (Greek: Άγιος Σπυρίδων), which is built on a tiny piece of land that is connected by a hand made bridge to the rest of the island.
