In the title compound, [AuI(C19H15OP)2], the complete mol­ecule is generated by the application of twofold symmetry. The AuI atom is in a trigonal–planar geometry within an IP2 donor set with the greatest distortion seen in the P—Au—P angle [128.49 (3) °]. Close intra­molecular Au⋯O inter­actions [3.172 (3) Å] are observed. No specific inter­molecular inter­actions are noted in the crystal packing.
