Diaminocyclohexanetetraacetic acid is an organic compound with the formula C₆H₁₀(N(CH₂CO₂H)₂)₂. It is an aminopolycarboxylic acid, structurally related to EDTA but with a chiral backbone derived from trans-1,2-diaminocyclohexane.

Among its many complexes are the 7-coordinate titanyl(IV), titanium(III), vanadium(III), and iron(III) derivatives. The Cr(III) derivative is 6-coordinate.
