Ruprecht 101 (or Ru 101, Rup 101) was discovered on photographic plates taken at the Boyden Observatory, South Africa, and first cataloged as open clusters. Ruprecht (1966) describes it as open cluster of Trumpler class III3p. Froebrich et.al. (2007) have included it in their list of nine new globular cluster candidates.
