Dipotassium phosphate (K₂HPO₄) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is the inorganic compound with the formula K₂HPO₄^.(H₂O)_x (x = 0, 3, 6). Together with monopotassium phosphate (KH₂PO₄^.(H₂O)_x) it is often used as a fertilizer, food additive, and buffering agent.

A dipotassium phosphate solution is formed by the stoichiometric reaction of phosphoric acid with two equivalents of potassium hydroxide:

H₃PO₄ + 2 KOH → K₂HPO₄ + 2 H₂O
