NGC 5082 is a lenticular galaxy in the constellation of Centaurus. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, three non-redshift measurements give a closer mean distance of . It was discovered by British astronomer John Herschel on 3 June 1834.
NGC 5082 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.
NGC 5082 group NGC 5082 is a member of a small group of galaxies named after it. The other two galaxies in the NGC 5082 group (also known as LGG 348) are and .
