We study the propagation of electromagnetic waves in the limit of geometrical
optics for a class of nearly transparent nonlinear uniaxial metamaterials for
which their permittivity tensors present a negative principal component. Their
permeability are assumed positive and dependent on the electric field. We show
that light waves experience triple refraction -- trirefringence. Additionally
to the ordinary wave, two extraordinary waves propagate in such media.
