  We consider different renormalizable models of Lorentz invariance violation.
We show that the limits on birefringence of the propagation of cosmic microwave
background photons from the five year data of the Wilkinson microwave
anisotropy probe (WMAP) can be translated into a limit of Lorentz symmetry
violation. The obtained limits on Lorentz invariance violation are stronger
than other published limits. We also cast them in terms of limits on a
birefringent effective photo "mass" and on a polarization dependence of the
speed of light.
