Sodium bromite is a sodium salt of bromous acid. Its trihydrate, NaBrO2·3H2O, has been isolated in crystal form. It is used by the textile refining industry as a desizing agent for oxidative starch removal.{{cite book |last1=Holleman |first1=A.

It is also used as an oxidizing agent for converting alcohols to aldehydes, such as the conversion of benzyl alcohol to benzaldehyde, and for the Hofmann degradation of amides to amines.{{cite journal |author1=Makoto Okawara |title=亜臭素酸ナトリウム |journal=Journal of Synthetic Organic Chemistry, Japan |date=1984 |volume=42 |issue=8 |pages=751–754 |doi=10.5059/yukigoseikyokaishi.42.751 |trans-title=Sodium bromite |language=Japanese|doi-access=free }}
