We present results of an Hi survey of the cluster of galaxies Abell 262, using the Westerbork Synthesis Radio Telescope (WSRT). Eleven galaxies were detected in five fields. In a few cases the gas in these galaxies shows an asymmetrical distribution; the most likely explanation is the interaction between the cluster medium and the gaseous disks. Only two of the detected galaxies are slightly Hi-deficient. At 40″ to the West of CGCG 160-049 we tentatively detect what may be an associated Hi cloud. The total mass of this cloud is , and no optical counterpart has yet been found.
