Trisodium borate is a chemical compound of sodium, boron, and oxygen, with formula Na3BO3, or (Na+)3[BO3]3−.[3] It is a sodium salt of the orthoboric acid B(OH)3.

The compound is also called trisodium orthoborate, sodium orthoborate, or just sodium borate. However, "sodium orthoborate" has been used also for a compound with formula Na4B2O5, which would correspond to an equimolar mixture of sodium metaborate NaBO2 and trisodium borate proper.[4] and "sodium borate" is sometimes used in the generic sense, for a sodium salt with any of several other borate anions.
