We present HI observations of 54 Hickson Compact Groups (HCG) of which 41 have been detected in the 21-cm line of neutral hydrogen. For 13 objects upper limits have been obtained. The integrated FORMULA values of the observed HCGs scatter over a large range of values showing strong HI-deficiencies for a great number of objects.

Key words: galaxies: clusters - galaxies: interstellar matter
