'''甲酸钡'''是[[钡]]的[[甲酸盐]]，[[化学式]] Ba(HCOO)<sub>2</sub>。

== 制备==
甲酸钡可以由[[氢氧化钡]]和[[甲酸]]中和而成。<ref name="Abegg">[[Richard Abegg]], [[Friedrich Auerbach]]: ''Handbuch der anorganischen Chemie, Bd. 2''. Verlag S. Hirzel, Leipzig 1908. S.&nbsp;286; [http://www.archive.org/stream/a2handbuchderano02abeguoft#page/286/mode/2up Volltext]</ref>
