Zirconium iodate is an inorganic compound with the chemical formula Zr(IO₃)₄. It can be prepared by reacting sodium iodate and zirconium sulfate tetrahydrate in an aqueous solution. The resulting precipitate is dried and refluxed in concentrated nitric acid.{{cite journal|journal=Acta Crystallographica|volume=14|issue=2|date=1961-02-10|pages=128–132|doi=10.1107/S0365110X6100053X|url=http://scripts.iucr.org/cgi-bin/paper?S0365110X6100053X|title=The crystal structure of Zr(IO3)4|accessdate=2021-06-01|author=A.
