We report the discovery of tidal tails around the high-latitude Galactic globular cluster NGC 5466 in Sloan Digital Sky Survey data. Neural networks are used to reconstruct the probability distribution of cluster stars in ugriz space. The tails are clearly visible once extragalactic contaminants and field stars have been eliminated. They extend 64 on the sky, corresponding to 61 kpc in projected length. The orientation of the tails is in good agreement with the cluster's Galactic orbit, as judged from the proper-motion data.
