In chemistry, a fluoroanion or fluorometallate anion is a polyatomic anion that contains one or more fluorine atoms. The ions and salts form from them are also known as complex fluorides. They can occur in salts, or in solution, but seldom as pure acids. Fluoroanions often contain elements in higher oxidation states. They mostly can be considered as fluorometallates, which are a subclass of halometallates.{{cite web |title=fluorometallate anion (CHEBI:51527) |url=https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI%3A51527 |website=www.ebi.ac.uk}}{{cite web |title=fluorometallate anion - Ontology Browser - Rat Genome Database |url=https://rgd.mcw.edu/rgdweb/ontology/view.html?acc_id=CHEBI:51527 |website=rgd.mcw.edu}}

Anions that contain both fluorine and oxygen can be called "oxofluoroanions" (or rarely "fluorooxoanions").
