Sklodowskite is a uranium mineral with the chemical formula: Mg(UO2)2(HSiO4)2·5H2O. It is a secondary mineral which contains magnesium and is a bright yellow colour, its crystal habit is acicular, but can form in other shapes. It has a Mohs hardness of about 2–3. It is named after the maiden name of Marie Skłodowska Curie.[2] It is the magnesium analogue of the much more common uranium mineral Cuprosklodowskite, which contains copper instead.

It was discovered by Alfred Schoep [de] (1881–1966) in 1924.
