Trichlorophenylsilane is a compound with formula Si(C<sub>6</sub>H<sub>5</sub>)Cl<sub>3</sub>.
Similarly to other alkylchlorosilanes, trichlorophenylsilane is a possible precursor to silicone. It hydrolyses in water to give HCl and phenylsilantriol, with the latter condensating to a polymeric substance.
