Giannitsou ({{langx|el|Γιαννιτσού}}) is a semi-mountainous village, altitude of ~300m above the sea level, in western Phthiotis/Central Greece, with about 400 inhabitants. It is located north of Makrakomi and 36 km northwest of Lamia. After the recent reorganization of administrative divisions (Kallikratis Plan) it is part of the municipality of Makrakomi. In walking distance from the village there is a pre-Ottoman-era settlement which is yet unexplored, called Lavanitsa.http://www.lavanitsa.gr/
