NGC 6324 is a spiral galaxy in the constellation of Ursa Minor. Its velocity with respect to the cosmic microwave background is 4,825±38 km/s, which corresponds to a Hubble distance of 232.1 ± 16.4 Mly (71.16 ± 5.04 Mpc). It was discovered by German-British astronomer William Herschel on 12 December 1797.

NGC 6324 has a possible active galactic nucleus, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.
