Greve in Chianti is a town and comune in the Metropolitan City of Florence, Tuscany, Italy. It is located about 31 kilometres south of Florence and 42 kilometres north of Siena. Sitting in the Val di Greve, it is named for the small, fast-flowing river that runs through it, is the principal town in the Chianti wine district that stretches south of Florence to just north of Siena. Until recently it has been a quiet, almost bucolic town because it was, and still is, well off the main roads.
