Triphenylarsine is the chemical compound with the formula As(C₆H₅)₃. This organoarsenic compound, often abbreviated AsPh₃, is a colorless crystalline solid that is used as a ligand and a reagent in coordination chemistry and organic synthesis. The molecule is pyramidal with As-C distances of 1.942–1.956 Å and C-As-C angles of 99.6–100.5°.

This compound is prepared by the Wurtz reaction of arsenic trichloride with chlorobenzene using sodium as the reducing agent:

AsCl₃ + 3 PhCl + 6 Na → AsPh₃ + 6 NaCl
