Phosphine (IUPAC aha: phosphane) bụ ihe mejupụtara ya na usoro kemịkal PH3. Ọ bụ gas na-enweghị agba, nke na-ere ọkụ, nke na-egbu egbu ma na-ekewa dị ka pnictogen hydride. Phosphine dị ọcha bụ ihe na-enweghị isi, mana ihe nlele nke teknụzụ nwere isi na-adịghị mma dị ka galik ma ọ bụ azụ na-ere ere, n'ihi ọnụnọ nke phosphine na diphosphane (P2H4). Site na traces nke P2H4 dị ugbu a, PH3 na-enwu ọkụ na ikuku (pyrophoric), na-ere ọkụ na-enwu ọkụ. Phosphines bụkwa otu ìgwè nke organophosphorus compounds na usoro R3 (RP = organic derivative). Organophosphines dị na catalysts ebe ha dị mkpa maka ion dị iche iche dị mgbagwoju; a na-enweta chiral catalyze site na phosphine?
