Mirabilite is a naturally occurring mineral with the chemical formula Na2SO4·10H2O. It belongs to the halide class of minerals and is a hydrated sodium sulfate. Mirabilite is typically found in arid or semi-arid environments where it forms through the evaporation of saltwater or salt lakes.

The mineral is usually white, colorless, or transparent in appearance, and exhibits a vitreous or glassy luster. It has a distincticular crystal structure, often with a tabular or platy habit. Mirabilite is relatively soft, with a hardness of about 2.5 on the Mohs scale, and it is soluble in water.

Mirabilite has a relatively low density, ranging between 1.7 and 1.9 g/cm³, and a high diathermancy, which allows it to transmit light clearly. It is an important mineral in the geological context, as it is often used as an indicator of the origin of other evaporite minerals.

The name "mirabilite" comes from the Latin "mirabilis," which means "wonderful" or "miraculous." The mineral was first described by the Swedish scientist Carlos Linneus in 1768. It is found in several parts of the world, including the Salt Lake in Israel, the Salt Valley in Utah, and the Gulf Coast of the United States.

Mirabilite is not typically used as a commercial mineral, due to its relatively soft and soluble nature. However, it is a significant component of salt deposits and is used in scientific studies to understand the properties of sulfate minerals in saline environments.
