Ferric citrate or iron(III) citrate is an ionic chemical compound with formula FeC
6H
5O
7, consisting of a trivalent iron anion (Fe3+
) and a trivalent citrate cation (C
6H
5O3−
7). It is a dark orangeish or reddish brown solid, slightly soluble in hot water yielding an orange or orange-yellow solution at pH < 2.0. The solution becomes green at pH > 2.0.

Sometimes the term is also used for the salt tetraferric tricitrate Fe
4(C
6H
4O
7)₃, where the citrate anions are fully deprotonated (C
6H
4O4−
7).
