Protaktinium trihidrida adalah sebuah senyawa anorganik dengan rumus kimia PaH3. Ia berstruktur isostruktural dengan uranium trihidrida dan dapat dibuat dengan mereaksikan protaktinium dan hidrogen pada suhu 250 °C dan tekanan 600 mmHg.[1] Perhitungan teoretis menunjukkan bahwa ia dapat membentuk lebih banyak senyawa yang mengandung hidrogen PaHn (n=4, 5, 8, 9) di bawah tekanan tinggi.[2] Protaktinium trihidrida cenderung sensitif terhadap udara lembap dan oksigen.
