'''Kalsitonin''' (juga dikenali sebagai '''tirokalsitonin''') ialah suatu [[hormon]] polipeptida linear asid asid 32-amino yang dihasilkan di dalam manusia terutamanya oleh sel [[sel parafolikel|parafolikel]] (juga dikenali sebagai sel C) bagi [[tiroid]], dan pada banyak lagi haiwan di dalam [[jasad ultimobrankium]].<ref name="Costoff_Calcitonin_Structure">{{Petik web|url=http://www.lib.mcg.edu/edu/eshuphysio/program/section5/5ch6/s5ch6_21.htm|title=Sect. 5, Ch. 6: Anatomy, Structure, and Synthesis of Calcitonin (CT)|author=Costoff A|authorlink=|coauthors=|date=|work=Endocrinology: hormonal control of calcium and phosphate|publisher=Kolej Perubatan Georgia|pages=|language=|archiveurl=|archivedate=|quote=|accessdate=7 Ogos 2008}}</ref> Hormon ini bertindak untuk mengurangkan [[kalsium]] darah (Ca<sup>2+</sup>), bertentangan dengan kesan [[hormon paratiroid]] (PTH).<ref name="isbn1-4160-2328-3">{{Petik buku|author=Boron WF, Boulpaep EL|authorlink=|editor=|others=|title=Medical Physiology: A Cellular And Molecular Approach|edition=|language=|publisher=Elsevier/Saunders|location=|year=2004|origyear=|pages=|chapter=Endocrine system chapter|quote=|isbn=1-4160-2328-3|oclc=|doi=|url=|accessdate=}}</ref> Kalsitonin telah dijumpai pada [[ikan]], [[reptilia]], [[burung]], dan [[mamalia]].
