'''二氮烯'''或'''二亚胺'''（HN=NH）是一种[[无机化合物]]，为[[烯烃]]（包括[[多烯]]）和[[炔烃]]的[[氢化]]试剂。氢化是顺式加成，两个氢从一面加到不饱和键上，与金属催化的氢化反应选择性类似，因此该法适用于某些不适合用金属催化加氢的烯烃。

二亚胺有[[顺反异构|顺式和反式]]两种，但只有顺式的可以与烯烃反应。它可看作是最简单的[[偶氮化合物]]。

二亚胺可通过[[过氧化氢]]在[[铜]]盐存在下氧化[[肼]]（见下面的方程式）或磺[[酰肼]]与碱反应（比如用[[碳酸氢钠]]处理三异丙基苯磺酰肼）得到。生成的是顺式和反式的混合物，很不稳定，会很快分解为氮和氢。一般生成二亚胺后便使其在原位与烯烃反应。
