In chemistry, furantetracarboxylic acid is an organic compound with formula C
₈H
₄O
₉, or (C₄O)(-(CO)OH)₄, which can be viewed as deriving from furan C
₄H
₄O through replacement of the four hydrogen atoms by carboxyl functional groups -(CO)OH.

By removal of four protons, the acid is expected to yield the anion C
₈O⁴⁻
₉, furantetracarboxylate, which is one of the oxocarbon anions (consisting solely of oxygen and carbon. By loss of 1 through 3 protons it forms the anions C
₈H
₃O⁻
₉, C
₈H
₂O²⁻
₉, and C
₈HO³⁻
₉, called respectively trihydrogen-, dihydrogen-, and hydrogenfurantetracarboxylate. The same names are used for the corresponding esters.

The acid can be obtained by from dioxalylsuccinate.^[1]^[2]^[3]

The salt rubidium trihydrogenfurantetracarboxylate RbH
₃C
₈O
₉ crystallizes as white needles.^[4]
