Cijanogen je hemijsko jedinjenje sa formulom (C N)₂. On je bezbojni, toksični gas opornog zadaha. Ovaj molekul je pseudohalogen. Cijanogenski molekuli se sastoje od dve CN grupe - analogno diatomskim halogenim molekulima, kao što je Cl₂, ali ima daleku manju oksidacionu sposobnost. Dve cijano grupe su vezane zajedno na njihovim atomima ugljenika: N≡C−C≡N, mada su i drugi izomeri poznati.^[7] Pojedini derivati cijanogena se takođe nazivaju "cijanogen" čak i kad sadrže samo jednu CN grupu. Na primer cijanogen bromid ima formulu NCBr.^[8]

Cijanogen je anhidrid oksamida:

H₂NC(O)C(O)NH₂ → NCCN + 2 H₂O

Oksamid se proizvodi iz cijanogena hidrolizom:^[9]

NCCN + 2 H₂O → H₂NC(O)C(O)NH₂
