Sodium metavanadate is the inorganic compound with the formula NaVO3. It is a yellow, water-soluble solid. Its natural forms include mineral metamunirite (anhydrous) and a dihydrate, munirite. Both are very rare, metamunirite is now known only from vanadium- and uranium-bearing sandstone formations of central-western USA and munirite from Pakistan and South Africa.
