Asam pirofosfat (disbeut juga Asam difosforik) adalah sebuah cairan yang dibentuk oleh dehidrasi asam fosfat dan garam, yang bersifat pirofosfat. Senyawa ini biasanya digunakan dalam pengobatan.
Asam pirofosfat termasuk asam anorganik, yaitu asam yang terbentuk dengan menghilangkan molekul air dari dua molekul asam fosfat, H4P2O7; Reaksi ini perlahan-lahan terbalik dengan air.
- H4P2O7 + H2O ⇌ 2H3PO4
