We report the detection of ethylene glycol (HOCH2CH2OH)
in comet C/1995 O1 (Hale-Bopp) from the analysis of archival radio
spectra. Its production rate is 
0.25% that of water,
making it one of the most abundant organic molecules in cometary
ices. This detection strengthens the similarity between interstellar
and cometary material.
