We show that the nonlinear massive gravity model of de Rham, Gabadadze, andTolley admits exact plane gravitational wave solution whose waveform obeys thetwo-dimensional Helmholtz equation. The solution is valid for arbitrary valuesof the coefficients of the cubic and quartic terms. In the massless limit thesolution reduces to the Aichelburg-Sexl metric in general relativity.
