**亞氨基鋰**是一種無機化合物，化學式為 Li 
2NH。它是一種白色貝殼狀晶體，在陽光下變為磚紅色。因為它此時轉變成了氨基鋰和氮化鋰:

　
: ${\rm {\ 2Li_{2}NH\rightarrow LiNH_{2}+Li_{3}N}}$

將混合物真空加熱，又變回白色。

它可以由氨基鋰熱分解來製備：

　
: ${\rm {\ 2LiNH_{2}\rightarrow Li_{2}NH+NH_{3}}}$

亞氨基鋰結構與氧化鋰類似，晶格常數為 504pm，密度 1.48g/cm3。它能與很多含活潑氫的有機物反應，不溶於苯等有機溶劑。

此外，亞氨基鋰還是一種有前途的儲氫材料。
