Trimagnesium phosphate is a compound with formula Mg3(PO4)2. It is a magnesium acid salt of phosphoric acid.

It can be formed by reaction of stoichiometric quantities of monomagnesium phosphate with magnesium hydroxide.

Mg(H2PO4)2+2 Mg(OH)2→Mg3(PO4)2•8H2O [1]

Found in nature in octohydrate form as the mineral bobierrite.[2]
