High-nuclear　rare-earth　incorporated　polyoxometalates（POMs）have　been　a　research　hotspot　in　the　fields　of　inorganic　synthetic　chemistry　and　material　chemistry.　Due　to　the　unique　electronic　arrangement　and　the　structural　characteristics　of　the　rare　earth　ions　and　the　excellent　properties　of　POMs，these　materials　have　promising　application　in　catalysis，magnetism，electrochemistry，sensor　probes　and　medicine　etc.　In　this　review，the　research　advance　of　high-nuclear　rare　earth　incorporated　POMs　in　the　past　three　decades　including　their　synthetic　strategies，structural　diversity，structure　modulation，and　related　properties　is　summarized.　In　addition，the　current　challenges　in　this　area　and　the　prospects　of　their　application　are　also　discussed.　©　2023　Chinese　Society　of　Rare　Earths.　All　rights　reserved.
