Kyparissia (Greek: Κυπαρισσία) is a town and a former municipality in northwestern Messenia, Peloponnese, Greece. Since the 2011 local government reform it is part of the municipality Trifylia, of which it is the seat and a municipal unit. The town proper has around 5,800 inhabitants.
The town is situated on the Gulf of Kyparissia, a bay of the Ionian Sea. It is 38 km north of Pylos, 46 km northwest of Kalamata and 51 km southeast of Pyrgos. The Greek National Road 9 (Pyrgos - Methoni) passes through the town. Kyparissia is the terminus of a now disused railway line from Kalo Nero, on the line from Pyrgos to Kalamata. The town has a port, which is mainly used for cargo purposes. On a hill east of the town centre lies a fortress built during the Frankish period.

The ancient Greek town Cyparissia (Ancient Greek: Κυπαρισσία) was already mentioned by Homer in his Iliad. It probably possessed an artificial harbour. In the Middle Ages, it was known as Arkadia, and it kept this name until it was destroyed in 1825 during the Greek War of Independence.
Under the Principality of Achaea, Kyparissia/Arkadia was the seat of the Barony of Arcadia, which was the last Frankish territory (except for the Venetian possessions) to fall to the Despotate of the Morea, in 1432.
