Charisia (Greek: Χαρισία) was a city in ancient Arcadia. It was part of the Eutresia region. Charisia was named after its founder Charisius, a son of Lycaon. It was abandoned when Megalopolis was founded.
It was located 10 stades (2 km) from Skias (itself 13 stades from Megalopolis) and 10 stades from Trikolonoi. The location of the ancient city has never been found, it is believed to have been situated in the area of the modern Trilofo.
