'''六フッ化ネプツニウム'''または'''フッ化ネプツニウム'''(VI)は化学式NpF<sub>6</sub>で表される[[ネプツニウム]]のフッ化物で、最大の酸化数のものである。橙色の揮発性結晶<ref name="GMELIN_108_114" />で、強い腐食性と放射能のため取り扱いは困難を極める。四フッ化ネプツニウム(NpF<sub>4</sub>) を単体フッ素などの強力なフッ化剤を用いてフッ化することによって得られる<ref name="NPF6_PREPARATION">John G. Malm, Bernard Weinstock, E. Eugene Weaver: „The Preparation and Properties of NpF<sub>6</sub>; a Comparison with PuF<sub>6</sub>“, ''J. Phys. ''</ref>。

: <chem>NpF4\ + F2 -> NpF6</chem>
また、[[三フッ化ネプツニウム]]のフッ化によっても得られる<ref>Sherman Fried, Norman Davidson: „The Preparation of Solid Neptunium Compounds“, ''[[米国化学会誌|J. Am. Chem.]]''</ref>。

: <chem>2NpF3\ + 3F2 -> 2 NpF6</chem>
