Sodium sulfide  is the chemical compound with the formula Na ₂ S, or more commonly its hydrate Na ₂ S·9H ₂ O. Both the anhydrous and the hydrated salts are colorless solids. They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na ₂ S and its hydrates emit hydrogen sulfide, an extremely toxic, flammable and corrosive gas which smells like rotten eggs.

Some commercial samples are specified as Na ₂ S· x H ₂ O, where a weight percentage of Na ₂ S is specified. Commonly available grades have around 60% Na ₂ S by weight, which means that  x  is around 3. Such technical grades of sodium sulfide have a yellow appearance owing to the presence of polysulfides. These grades of sodium sulfide are marketed as 'sodium sulfide flakes'.

Reagent in organic chemistry

Alkylation of sodium sulfide give thioethers:

Even aryl halides participate in this reaction. By a broadly similar process sodium sulfide can react with alkenes in the thiol-ene reaction to give thioethers. Sodium sulfide can be used as nucleophile in Sandmeyer type reactions. Sodium sulfide reduces1,3-dinitrobenzene derivatives to the 3-nitroanilines. Aqueous solution of sodium sulfide can be refluxed with nitro carrying azo dyes dissolved in dioxane and ethanol to selectively reduce the nitro groups to amine; while other reducible groups, e.g. azo group, remain intact. Sulfide has also been employed in photocatalytic applications.
