Molaoi (Greek: Μολάοι) is a town and a former municipality in Laconia, Peloponnese, Greece. Since the 2011 local government reform it is part of the municipality Monemvasia, of which it is the seat and a municipal unit. The population in 2011 was 4,980, of which 2,534 lived in the town itself.
The name of the village derived from the Latin word Mola (mill). Mola was mentioned for first time in the Treaty of Sapienza (1209). The current name Molaoi was mentioned during 15th century. During late medieval and early Ottoman era, Molaoi reamined a small village, overshadowed by nearby Monemvasia. Molaoi was destroyed during the Orlov Revolt. The village was destroyed again by Ibrahim in 1825, during the Greek War of Independence. After Greek independence was achieved, Molaoi increased its population, receiving residents from Monemvasia, Crete, the Mani peninsula and nearby villages. It then evolved into a local administrative centre.
