'''五氟化镎'''，又称'''氟化镎(V)'''是一种[[无机化合物]]，由[[镎]]和[[氟]]组成，[[化学式]] NpF<sub>5</sub>。

==制备==

五氟化镎可以由[[六氟化镎]]与[[碘]]化合而成：<ref name=r1/>

:<math>\mathrm{10\ NpF_6\ +\ I_2\  \longrightarrow \ 10\ NpF_5\ +\ 2\ IF_5}</math>

[[五氟化碘]]会以副产物的形式生成。

==性质==
五氟化镎会在 318 °C 下分解，形成[[四氟化镎]] 和[[六氟化镎]]。 和[[五氟化铀]]不同，五氟化镎不与[[三氯化硼]]反应， 不过它会和[[氟化锂]] 在[[氟化氢|HF]] 反应，形成LiNpF<sub>6</sub>。<ref name=r1/>
