The Formiche di Grosseto ("Ants of Grosseto") is a group of islets which emerge sharply in the Tuscan Archipelago. They are located in open sea among the coast of the Natural Park of Maremma and Pianosa, approximately 13 nautical miles (24 km) from Porto Santo Stefano on Monte Argentario and 9.4 miles (15.1 km) from Marina di Grosseto; they are part of the comune of Grosseto and are placed in a nature reserve which makes part of a special protection area.
