Perphenazine is a typical antipsychotic drug. Chemically, it is classified as a piperazinyl phenothiazine. Originally marketed in the United States as Trilafon, it has been in clinical use for decades.

Perphenazine is roughly ten times as potent as chlorpromazine at the dopamine-2 (D2) receptor; thus perphenazine is considered a medium-potency antipsychotic.
