Cadmium sulfite is an inorganic compound with the formula CdO3S. [2] It is the cadmium salt of sulfuric acid. Several hydrates of cadmium sulfite are known, with the dihydrate (CdO3S·2H2O) being notable. Cadmium sulfite crystallizes from aqueous solutions. [3]

As with most other cadmium compounds, it is toxic to the liver and reproductive system. [2]

Cadmium sulfite has been used to prepare nanoparticles of cadmium oxide by the calcination of a cadmium sulfite emulsion. [4]
