<jats:title>Abstract</jats:title><jats:p>A high‐pressure high‐temperature synthesis involving initial reaction, nitrogen depletion and annealing yields a new ϵ‐type iron iridium nitride. Energy dispersive X‐ray spectroscopy of metallographic samples evidence a main phase having a molar metal ratio of Fe:Ir = 2:1 within experimental error. Chemical analyses and thermogravimetric measurements quantify the nitrogen content to 1.07 wt % (<jats:italic>x</jats:italic> = 0.24) and 1.2 wt % (<jats:italic>x</jats:italic> = 0.27), respectively. Above 750 K, the phase Fe<jats:sub>2</jats:sub>IrN<jats:sub>0.24</jats:sub> decomposes into solid solutions ϵ‐Fe(Ir) and γ‐Fe(Ir) involving the release of N<jats:sub>2</jats:sub> at ambient pressure. Magnetic susceptibility data suggest long‐range antiferromagnetic ordering at <jats:italic>T</jats:italic><jats:sub>N</jats:sub> = 27 K.</jats:p>
