Dicalcium phosphate (DCP) is the calcium phosphate with the formula CaHPO₄. It can also be called dibasic calcium phosphate or calcium monohydrogen phosphate. Dicalcium phosphate is used as a food additive, as a polishing agent, and as a feed additive.

As a valuable source of calcium and phosphates it is often found breakfast cereals as a supplement. It is also used in animal feed products such as dog treats and poultry feed. 

DCP also exhibits good anti-caking properties alongside its nutritional benefits in food and feed products.
