氨基钠是一个无机化合物，化学式为NaNH₂。室温下纯品为白色固体，试剂常带金属铁而呈灰色。氨基钠与水强烈反应，是有机合成中常用的强碱。

氨基钠可由钠与氨气反应， 或硝酸铁催化下钠与液氨的反应来制备。后者反应在氨沸点（约-33°C）时反应最快，也更常用：

2 Na + 2 NH₃ → 2 NaNH₂ + H₂

NaNH₂为类盐固体，晶格中 钠原子为四面体结构。 溶于氨时，NaNH₂溶液存在Na(NH₃)₆和NH₂离子，可导电。

Sodium amide, commonly called sodamide, is the inorganic compound with the formula NaNH₂. This solid, which is dangerously reactive toward water, is white, but commercial samples are typically gray due to the presence of small quantities of metallic iron from the manufacturing process. Such impurities do not usually affect the utility of the reagent. NaNH₂ conducts electricity in the fused state, its conductance being similar to that of NaOH in a similar state. NaNH₂ has been widely employed as a strong base in organic synthesis.
