In organic chemistry, a tricarbonate is a compound containing the divalent –O–C(=O)–O–C(=O)–O–C(=O)–O– functional group, which consists of three carbonate groups linked in a chain by sharing of oxygen oxygen atoms. These compounds can be viewed as derivatives of a hypothetical tricarbonic acid, HO–C(=O)–O–C(=O)–O–C(=O)–OH. An important example is di-tert-butyl tricarbonate (H
3C–)
3C–C
3O
7–C(–CH
3)
3, an intermediate in the synthesis of di-tert-butyl dicarbonate.

The term tricarbonate is sometimes used for salts that contain three carbonate dianions in their covalent structure or stoichiometric formula, such as cerium tricarbonate Ce
2(CO
3)
3.
