Follonica (Italian pronunciation: [folˈlɔːnika]) is a town and comune (township) of province of Grosseto in the Italian region of Tuscany, on the Gulf of Follonica (Golfo di Follonica), about 40 kilometres (25 mi) northwest of the city of Grosseto.

It was founded in 1834 by Grand Duke Leopold II of Tuscany for the workers of a new ironworks plant. However, the area was already settled in Etruscan and Roman times, and a medieval castle (Castello di Valli), whose ruins overlook now the modern town from a nearby hill, existed since at least 884. Until 1923 it was a frazione of Massa Marittima.

Follonica is a tourist site during the summer, mostly visited by the Italians themselves, lately, it has been visited from other people from other countries, such as Germany, France and United Kingdom. The city has been awarded the Bandiera Blu ("Blue Flag") every year from 2000 to 2007 for the cleanliness of its beaches and seawater.
