Uniaxially anisotropic chiral media are quite easy to be realized artificially, where the chirality appears only in one direction. In this report, we investigate the refractive properties of a plane wave incident from free space to such uniaxially chiral media. We show that different negative phase or group refractions occur in one or two eigenwaves simultaneously or separately. Hence, the uniaxially chiral media may support more kinds of negative refractions than isotropic chiral media and the left-handed materials. In the uniaxially chiral proposal, the condition to realize the negative refraction can be quite loose.
