Phosphine (IUPAC jina: phosphane) ni kiwanja na kemikali formula PH3. ni colorless, flammable, sumu gesi na ni classified kama pnictogen hydride. safi phosphine ni odorless, lakini sampuli ya kiufundi daraja na harufu mbaya sana kama vitunguu au samaki rotting, kutokana na kuwepo kwa substituted phosphine na diphosphane (P2H4). na athari ya P2H4 sasa, PH3 ni spontaneously flammable katika hewa (pyrophoric), kuchoma na moto luminous. Phosphines pia ni kundi la organophosphorus misombo na formula R3 (RP = kikaboni derivative). Organophosphines ni muhimu katika catalysts ambapo wao ni muhimu kwa ions mbalimbali tata ya chuma; catalyze kutoka phosphine derivatives.
