NGC 6528 is a globular cluster in the constellation Sagittarius, and is listed in the New General Catalogue. It has an apparent magnitude of about 11 and a diameter of about 16 arcminutes, and its Shapley–Sawyer Concentration Class is V, containing stars of 16th magnitude and dimmer. Dreyer described it as "pF, cS, R", meaning poor and faint, considerably small and round.
