Triphenylstibine is the chemical compound with the formula Sb(C₆H₅)₃, which is often abbreviated SbPh₃, This colourless solid is a common organoantimony(III) compound. It serves as a ligand in coordination chemistry{{cite book|editor=C. A. McAuliffe|title=Transition Metal Complexes of Phosphorus, Arsenic, and Antimony Ligands|publisher=J. Wiley|year=1973|isbn=0-470-58117-4}} and as a reagent in organic synthesis.

Like the related molecules triphenylamine, triphenylphosphine and triphenylarsine, SbPh₃ is pyramidal with a propeller-like arrangement of the phenyl groups. The Sb-C distances average 2.14-2.17 Å and the C-Sb-C angles are 95°.Adams, E. A.; Kolis, J. W.; Pennington, W. T.
