'''셀레늄산'''(Selenic acid)은 [[화학식]] {{chem2|H2SeO4}}을 갖는 [[무기 화합물]]이다. [[셀레늄]]의 [[산소산]]이며 그 구조는 {{chem2|(HO)2SeO2}}로 더 정확히 나타낼 수 있다. 무색의 화합물이다. 거의 쓰임이 없으나 파생물 [[셀레늄산 나트륨]]은 유리와 동물 먹이 생산에 사용된다.<ref name=Ullmann>Bernd E. Langner "Selenium and Selenium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. {{DOI|10.1002/14356007.a23_525}}.</ref>
