The Maremma (/məˈrɛmə/, Italian: [maˈremma]; from Latin maritima, "maritime [land]") is a coastal region of western central Italy, bordering the Tyrrhenian Sea.

It was formerly mostly marshland, often malarial, but was drained by order of Ferdinando I de' Medici.

It was traditionally populated by the butteri, mounted cattle herders who rode horses fitted with one of two distinctive styles of saddle, the scafarda and the bardella.

The central part corresponds approximately with the province of Grosseto, extending northward to the Colline Metallifere and the slopes of Monte Amiata, but the region extends northward from Piombino to the mouth of the Cecina, and southwards into Lazio as far as Civitavecchia.

[1] The Maremma has given rise to, or given its name to, several breeds of domestic animal.
