'''HV 2112''' adalah [[bintang variabel]] bercahaya dingin di [[Awan Magellan Kecil]]. Hingga 2018, ia dianggap sebagai kandidat yang paling mungkin untuk objek [[Objek Thorne–Zytkow|Thorne–Żytkow]], tetapi sekarang dianggap sebagai bintang [[Cabang raksasa asimtotik|cabang raksasa yang asimtotik]].
