'''칼륨 명반'''(Potassium alum), '''포타슘 알룸''', '''칼륨 백반'''은 화학식 KAl(SO<sub>4</sub>)<sub>2</sub>을 갖는 [[칼륨]], [[알루미늄]]의 복[[황산염]]인 [[화합물]]이다. [[수화물]] KAl(SO<sub>4</sub>)<sub>2</sub>·12H<sub>2</sub>O로서 자주 마주친다. [[백반 (화학)|백반]]으로 불리는 일반 등급의 화합물들 중 가장 중요한 화합물이며 간단히 백반(alum)으로도 부른다.<ref>{{서적 인용|author1=Bottomley, L. |author2=Bottomley, L.A. |title=Chemistry 1310: Laboratory Manual|publisher=School of Chemistry & Biochemistry, Georgia Institute of Technology and Hayden-McNeil Publishing|location=Plymouth, MI|year=2010 |isbn=978-0-7380-3819-3}}</ref>
