Antiperovskite　manganese　nitrides　are　a　group　of　negative　thermal　expansion　(NTE)　materials　that　have　been　developed　rapidly　in　recent　years.　They　exhibit　important　potential　applications　due　to　isotropic　NTE　property,　controllable　coefficient　of　NTE　and　NTE　operation　temperature　window,　and　good　metallic　and　mechanical　properties.　In　this　review,　state　of　the　arts　and　recent　development　in　the　field　of　studying　antiperovskite　manganese　nitrides　have　been　summarized　and　commented,　which　consist　of　introduction　of　history,　classification,　preparation　approaches,　influencing　factors　and　mechanisms　of　NTE　for　such　materials.　The　prospects　are　also　described　for　antiperovskite　manganese　nitrides.
