  We derive the exact gravitational wave solutions in a general class of
quadratic Poincar\'e gauge gravity models. The Lagrangian includes all possible
linear and quadratic invariants constructed from the torsion and the curvature,
including the parity odd terms. The ansatz for the gravitational wave
configuration and the properties of the wave solutions are patterned following
the corresponding ansatz and the properties of the plane-fronted
electromagnetic wave.
