Cobalt(II) oxalate is the inorganic compound with the formula of CoC₂O₄. Like other simple inorganic oxalates, it is a coordination polymer. The oxalate ligands bridge of Co(OH₂)₂ centres. Each cobalt adopts octahedral coordination geometry.^[1]

It is used in the preparation of cobalt catalysts, and cobalt metal powder for powder-metallurgical applications. It is made in process of recycling lithium-ion bateries, where the cobalt is obtained from cathode material (LiCoO₂) by leaching with sulfuric acid and then precipitated with ammonium oxalate.
