'''옥살산칼슘'''(Calcium oxalate)은 [[화학식]] {{chem2|CaC2O4}}을 갖는 [[옥살산]]의 [[칼슘]][[염]]이다. 수화물 {{chem2|CaC2O4*''n''H2O}}을 이루며 여기서 n은 1~3까지 다양하다. 무수 형태와 모든 수화물 형태가 무색이거나 백색이다.

== 의학적 중요성 ==
옥살산칼슘은 흡입 시 따끔거림과 마비를 유발할 수 있고 심지어는 치명적일 수 있다.
=== 신장결석 ===
{{본문|신장결석}}
신장결석의 약 76%가 부분적으로 또는 온전히 옥살산칼슘 유형이다.<ref name="Singh">{{저널 인용|last1=Singh |first1=Prince |last2=Enders |first2=Felicity T. |last3=Vaughan |first3=Lisa E. |last4=Bergstralh |first4=Eric J. |last5=Knoedler |first5=John J. |last6=Krambeck |first6=Amy E. |last7=Lieske |first7=John C. |last8=Rule |first8=Andrew D. |title=Stone Composition Among First-Time Symptomatic Kidney Stone Formers in the Community |journal=Mayo Clinic Proceedings |date=October 2015 |volume=90 |issue=10 |pages=1356–1365 |doi=10.1016/j.mayocp.2015.07.016|pmid=26349951 |pmc=4593754 }}</ref> 소변이 지속적으로 칼슘과 수산염으로 포화될 때 형성된다. 전 세계 1~15%의 사람들이 어느 시점에서 신장결석의 영향을 받는다.<ref name=BMJ2016>{{저널 인용|last1=Morgan|first1=Monica S C|last2=Pearle|first2=Margaret S|title=Medical management of renal stones|journal=BMJ|year=2016|volume=352|pages=i52|issn=1756-1833|doi=10.1136/bmj.i52|pmid=26977089|s2cid=28313474}}</ref><ref name=":3">{{저널 인용|date=6 September 2020|title=Prevalence and Trends in Kidney Stone Among Adults in the USA: Analyses of National Health and Nutrition Examination Survey 2007–2018 Data|url=https://www.sciencedirect.com/science/article/abs/pii/S2405456920302248|journal=European Urology Focus|language=en|doi=10.1016/j.euf.2020.08.011|issn=2405-4569|last1=Abufaraj|first1=Mohammad|last2=Xu|first2=Tianlin|last3=Cao|first3=Chao|last4=Waldhoer|first4=Thomas|last5=Seitz|first5=Christian|last6=d'Andrea|first6=David|last7=Siyam|first7=Abdelmuez|last8=Tarawneh|first8=Rand|last9=Fajkovic|first9=Harun|last10=Schernhammer|first10=Eva|last11=Yang|first11=Lin|last12=Shariat|first12=Shahrokh F.|volume=7 |issue=6 |pages=1468–1475 |pmid=32900675|s2cid=221572651}}</ref> 2015년, 이로 인해 전 세계적으로 약 16,000명의 사망자를 냈다.<ref name=GBD2015De>{{저널 인용| vauthors = Vos T, Allen C, Arora M, Barber RM, Bhutta ZA, Brown A, etal | collaboration = GBD 2015 Disease and Injury Incidence and Prevalence Collaborators | title = Global, regional, and national life expectancy, all-cause mortality, and cause-specific mortality for 249 causes of death, 1980–2015: a systematic analysis for the Global Burden of Disease Study 2015 | journal = Lancet | volume = 388 | issue = 10053 | pages = 1459–1544 | date = October 2016 | pmid = 27733281 | pmc = 5388903 | doi = 10.1016/s0140-6736(16)31012-1 }}</ref>
