'''옥살산염'''({{llang|en|oxalate}})은 [[화학식]]이 C<sub>2</sub>O<sub>4</sub><sup>2−</sup>인 [[음이온]]이다. IUPAC명은 '''에테인다이오에이트'''({{llang|en|ethanedioate}})이다. 이 [[음이온|이음이온]]은 무색이다. 옥살산염은 일부 식품을  포함하여 자연적으로 생성된다. 옥살산염은 [[옥살산 나트륨]](Na<sub>2</sub>C<sub>2</sub>O<sub>4</sub>)과 같은 다양한 [[염]]과 [[옥살산 다이메틸]](C<sub>2</sub>O<sub>4</sub>(CH<sub>3</sub>)<sub>2</sub>)과 같은 여러 [[에스터]]를 생성한다. 옥살산염은 [[옥살산]]의 [[짝염기]]이다. 수용액의 중성 pH에서 옥살산은 완전히 옥살산염으로 전환된다.
