Sodium percarbonate or sodium carbonate peroxide is an inorganic compound with the formula 2 Na2CO3 · 3 H2O2. It is an addition compound, specifically a co-crystal, formed by sodium carbonate ("soda ash" or "washing soda") and hydrogen peroxide (that is, a perhydrate). It is a colorless, crystalline, hygroscopic, and water-soluble solid. It is sometimes abbreviated as SPC. It contains 32.5% by weight of hydrogen peroxide.

The product is used in some eco-friendly bleaches and other cleaning products.
