Trioxoglutaric acid^[1] or trioxopentanedioic acid is a hypothetical chemical compound with formula C₅H₂O₇ or HO−(C=O)₅−OH. It can be seen as a derivative of glutaric acid, hence its common name. It would be the next member of the series of fully oxidized straight-chain dicarboxylic acids, that starts with the oxalic, oxomalonic, and dioxosuccinic acids.

Removal of two protons from the molecule would yield the trioxoglutarate anion, C
₅O²⁻
₇ or ⁻O−(C=O)₅−O⁻. This would be one of the oxocarbon anions, which consist solely of carbon and oxygen. The name would also be used for salts containing that anion, and for esters with the [−O−(C=O)₅−O−] moiety.

Removal of a single proton would result in the monovalent anion hydrogentrioxoglutarate, C
₅HO⁻
₇ or HO−(C=O)₅−O⁻.
