Phosphine (magaca IUPAC: fosphane) waa walax leh caanaha kiimikada ee PH3. Waa gaas aan midab lahayn, guban kara, sun ah waxaana loo kala saaraa sida pnictogen hydride. Phosphine saafi ah waa ur la'aan, laakiin shaybaarada heerka farsamada waxay leeyihiin ur aan fiicnayn sida toonta ama kalluunka burburay, sababtoo ah joogitaanka phosphine iyo diphosphane (P2H4). Iyada oo raadadka P2H4 ay joogaan, PH3 si iskeed ah ayuu ugu guban karaa hawada (pyrophoric), oo ku gubanaya olol dhalaalaya. Phosphines sidoo kale waa koox ka mid ah xeryahooda organophosphorus oo leh caanaha R3 (RP = dabiiciga dabiiciga ah). Organophosphines waxay ku jiraan kiciyeyaasha halkaasoo ay muhiim u yihiin ion-yada birta ee kala duwan; ka soo baxa phosphine waxay siiyaan qalab kaadi kara kiciyaal, waxay siiyaan alaabada kiimikada ee Phosphine.
