Acetaldehyde ammonia trimer is a chemical compound described by the formula (CH₃CHNH)₃. The pure material is colourless but samples often appear light yellow or slightly beige due to the degradation by oxidation. It is hygroscopic, and can be found in a trihydrate form.

As implied by its name, it is a trimeric species formed from the reaction of acetaldehyde and ammonia:: 3 CH₃CHO + 3 NH₃ → (CH₃CHNH)₃ + 3 H₂O

Studies using NMR spectroscopy indicate that the three methyl groups are equatorial, thus the molecule has C_3v point group symmetry. [Nielsen, A. T.; Atkins, R. L.; Moore, D. W.; Scott, R.

The compound is related to hexamethylenetetramine, which is the condensation product of the condensation of ammonia and formaldehyde.
