'''フッ化ネプツニウム(V)'''(Neptunium(V) fluoride)は、[[ネプツニウム]]と[[フッ素]]からなる化学式NpF<sub>5</sub>の化合物である。

==合成==
[[フッ化ネプツニウム(VI)]]と[[ヨウ素]]の反応で合成することができる<ref name=r1/>。副生物として[[五フッ化ヨウ素]]が生成する。
:<math>\mathrm{10\ NpF_6\ +\ I_2\  \longrightarrow \ 10\ NpF_5\ +\ 2\ IF_5}</math>

==性質==
318℃で[[熱分解]]し、[[フッ化ネプツニウム(IV)]]とフッ化ネプツニウム(VI)になる。[[フッ化ウラン(V)]]とは異なり、[[三塩化ホウ素]]とは反応せず、無水[[フッ化水素]]中で[[フッ化リチウム]]と反応し、LiNpF<sub>6</sub>を生成する<ref name=r1/>。
