Neodymium(III) phosphate is an inorganic compound, with the chemical formula of NdPO<sub>4</sub>.
Neodymium(III) phosphate hemihydrate can be obtained by the reaction of neodymium(III) chloride and phosphoric acid:
Its anhydrous form can be obtained by the reaction of silicon pyrophosphate (SiP<sub>2</sub>O<sub>7</sub>) and neodymium(III) fluoride.
Neodymium(III) phosphate reacts with calcium pyrophosphate to obtain Ca<sub>9</sub>Nd(PO<sub>4</sub>)<sub>7</sub>.
