La celestina o celestita es una variedad mineral de y la principal fuente del estroncio. Su nombre deriva de 'caelestis', en alusión al color azul de una de sus variedades. Su fórmula química es SrSO4. Es de la clase de los sulfatos, y de la subclase de los sulfatos anhidros. Pertenece al grupo de la baritina, porque tiene propiedades muy parecidas a las de la barita (Sulfato de Ba).
