Trifosforna kiselina ili tripolifosforna kiselina – čija je formula H5P3O10 – je kondenzirani oblik fosforne kiseline. U porodici fosfoernr kiseline i fosfati, to je slijedeća polifosforna kiselina nakon pirofosforne, H4P2O7, također zvane i difosforna kiselina.[1][2][3][4]

Spojevi kao ATP (adenozin-trifosfat) su esatri trifosforne kiseline.

Trifosforna kiselina nije dobijena u kristalnom obliku. Ravnotežne smjese s ukupnim sastavom, koje odgovaraju H5P3O10, sadrže oko 18% trifosforne kiseline. Otopina čiste kiseline može se dobiti izmjenom iona natrijeve soli, natrij-trifosfata, pri 0 °C.[5]

Poznate su razne vrijednosti pKa: 1,0 ; 2,2 ; 2,3 ; 3,7; 5,7 ; 8,5.
