The Pierre Auger collaboration has reported a correlation between Ultra-HighEnergy Cosmic Rays (UHECR) and nearby Active Galactic Nuclei (AGNs) within 75Mpc. Two of these events fall within 3 degrees from Centaurus A, the nearestAGN, clearly suggesting that this object is a strong UHECR emitter. Here wepursue this hypothesis and forecast the expected rate of ultra-high energyneutrinos in detectors like IceCube. In our baseline model we find a rate of0.4--0.6 yr^-1 events above a threshold of 100 TeV, the uncertainty of which ismainly related to the poor knowledge of the physical parameters of the sourceand on the details of the model. This situation will improve with detailed highenergy gamma ray measurements of Cen A by the upcoming GLAST satellite. Thiswould make Cen A the first example where the potential of high energymulti-messenger astronomy is finally realized.
