Abstract: We present the catalog of galaxy groups in the Local Supercluster. Ouralgorithm bases on assumption that a total energy of physical pair of galaxiesmust be negative. About 54% of the galaxies in our sample have been gathered in1082 groups. The groups are characterized by velocity dispersion 74 km-s andharmonic radius 204 kpc. These values are typical for small groups like LocalGroup or M81.
