**五氟化鏷**是一種鏷的氟化物，化學式 PaF5。

## 製備

五氟化鏷可以由五氧化二鏷和三氟化溴或五氟化溴在 600 °C 下反應而成。

　
: ${\ce {3 Pa2O5 + 10 BrF3 (6 BrF5) -> 6 PaF5 + 5 Br2 (3 Br2 ) + 7,5 O2}}$

它也可以由五氯化鏷或四氟化鏷和氟氣在 700 °C 下反應而成。

　
: ${\ce {2 PaF4 + F2 -> 2 PaF5}}$

水合五氟化鏷可以由五氧化二鏷和氫氟酸水溶液反應而成。

　
: ${\ce {Pa2 O5 + 10 HF -> 2 PaF5 . 2 H2O + 6 H2O}}$

它也可以由含氟的鏷配合物分解而成。
