2,6-Diformylpyridine is an organic compound with the formula C₅H₃N(CHO)₂, and typically appears as a solid powder at room temperature. The molecule features formyl groups adjacent to the nitrogen of pyridine. The compound is prepared by oxidation of 2,6-dimethylpyridine.

It condenses with amines to give diiminopyridine ligands, as was demonstrated in Fraser Stoddart's synthesis of molecular Borromean rings. It also finds use in the preparation of metal-coordinated polymer materials.
