'''황산 칼륨'''(미국: potassium sulfate, 영국: potassium sulphate, sulphate of potash, SOP, arcanite, potash of sulfur)은 화학식 K<sub>2</sub>SO<sub>4</sub>을 갖는 [[무기 화합물]]이다. 물에 [[용해도|용해]]되는 흰색 고체이다. [[비료]]에 흔히 사용되며 [[칼륨]]과 [[황]]을 모두 제공한다.

== 역사 ==
황산 칼륨이 알려지기 시작한 것은 14세기 초부터이다. [[요한 루돌프 글라우버]], [[로버트 보일]], [[타케니우스]]에 의해 연구되었다.
