This cluster was discovered by Paris Pismis from Tonantzintla Observatory in Mexico in 1959 (Pismis 1959), and cataloged as Tonantzintla 2 or Ton 2. It is one of two globulars listed in that paper, the other one is Tonantzintla 1 or Ton 1 - however, that other cluster turned out to be a duplicate rediscovery of NGC 6380. Ton 2 was also referred to as Pismis 26 in reference to that paper.
