Triphenylamine is an organic compound with formula (C₆H₅)₃N. In contrast to most amines, triphenylamine is nonbasic. Its derivatives have useful properties in electrical conductivity and electroluminescence, and they are used in OLEDs as hole-transporters.

Triphenylamine can be prepared by arylation of diphenylamine.
