Limonite is an iron ore, containing a hydrated iron (III) oxide-hydroxide mixture in different compositions. It is one of the two major iron ores, the other being hematite - used in the production of iron. It was named by Johann Friedrich Ludwig Hausmann in 1813 after the Greek word for meadow, indicating its common occurrence in lowlands.

Iron ore refers to rocks or minerals from which metallic iron is extracted for commercial use. These minerals appear dark grey to rusty red in color, and are usually rich in iron oxides. Iron occurs in these ores in the form of such chemical compounds as hematite, magnetite, siderite, limonite, or geothite.
