'''황산 마그네슘'''(magnesium sulfate 또는 magnesium sulphate)은 MgSO<sub>4</sub> 화학식을 갖는 [[화합물]]이자 [[염]]이다. [[마그네슘]] 양[[이온]] {{chem2|Mg(2+)}}(20.19% 질량)와 [[황산염]] 음이온 {{chem2|SO4(2-)}}로 구성된다. 백색의 [[결정]]으로, 물에는 녹지만 [[에탄올]]에는 녹지 않는다.

주 용도는 농업에서 토양의 마그네슘 문제를 해결하는 것이다. 마그네슘은 식물의 필수 영양소인데, 마그네슘이 [[엽록소]]와 [[광합성]] 역할을 하기 때문이다.
