Two-aperture optical and near-infrared polarization and flux measurements of the radio elliptical galaxy IC 5063 are presented. Analysis of the polarized flux shows that the large infrared excess in the nucleus most likely arises from a steep-spectrum non-thermal source with a polarization of 17 per cent and near-infrared luminosity 6×1041erg s-1. This result suggests that IC 5063 is closely related to the more luminous blazars. The origin of the polarization in the optical is, however, not clear.
