'''硒化鈉'''是一種無機化合物，由[[硒]]和[[鈉]]，為一種[[氫硒酸]]鹽，其化學式為Na<sub>2</sub>Se。

== 制備 ==
可用[[硫化鈉]]的制法，因為它們都是同族化物，具有類似性質，可由[[钠]]和[[硒]]在[[氨]]中或[[萘]]的存在下于[[四氢呋喃]]中反应即生成硒化钠。<ref>{{cite journal en| author = J.-H. So and P. Boudjouk | title = Hexamethyldisilathiane | editor = N. G. Russell | journal = Inorganic Syntheses | year = 1992 | doi = 10.1002/9780470132609.ch11}}</ref>

: 2Na + Se → Na<sub>2</sub>Se

== 晶體結構 ==
硒化鈉晶體結構為反[[螢石]]型結構，和其他[[鹼金屬]]硒化物類似，空間群為<math>Fm\bar{3}m</math>，每單位晶胞有4個單位<ref name="Lax"/>。
