The population of Agios Nikolaos is made up of residents of two villages from various origins. The inhabitants of the village Agios Nikolaos immigrated from the region Mani in Peloponnese and the inhabitants of the local origin of the village Agios Georgios.

Due lack of comprehensive records an exact date when Agios Nikolaos actually was founded is not available. According to few documents the village was established in the 16th century. According local traditions the settlement exists since the 14th century. Probable the village originally was situated directly on the coast. Pirate riots forced the people to move further inland. Pirate attacks were a common threat in the history of Chalkidiki and let many residents to leave their coastal places to resettle in higher regions. Evidence of an ancient settlement can be seen in the ruins of a fortification of byzantine origin from the 14th century. The ruins of the tower are located at the homonymous Pyrgos-beach (Pyrgos, Greek πύργος, tower).

It is assumed that Agios Nikolaos is located on the area of the ancient town Singos. Singos was founded by settlers from the southwest region Chalcis. The city survived the Persian Invasion. Chalkidiki was on the line of approach of the Persian troops. Many residents were forcibly recruited. After the Persians were defeated Singos joined the Delian League. Before the outbreak of the Peloponnesian War, Singos left the union to join an alliance with the city Potideia. On a Decree of King Peridiccas most inhabitants left their cities on the peninsula to settle down in the ever-growing Olynthos. After war the treaty "peace of Nicias' was signed but only few residents returned back to their hometowns. Further records of the historical course of Singos after 421 BC do not exist. When the city finally was abandoned or destroyed is unknown.
