Acetoguanamine is an organic compound with the chemical formula (CNH₂)₂CCH₃N₃. It is related to melamine but with one amino group replaced by methyl. Acetoguanamine is used in the manufacturing of melamine resins. Unlike melamine ((CNH₂)₃N₃), acetoguanamine is not a crosslinker. The "aceto" prefix is historical, the compound does not contain an acetyl group. A related compound is benzoguanamine.{{cite encyclopedia|author1=H. Deim |author2=G. Matthias |author3=R. A.

The compound is prepared by condensation of cyanoguanidine with acetonitrile:

:(H₂N)₂C=NCN + MeCN → (CNH₂)₂(CMe)N₃
