The M83 group of galaxies

M83 (NGC 5236)
NGC 5128 (Centaurus A, Dun 482)
NGC 5253 (H 2.638)
NGC 4945 (Dunlop 411)
NGC 5102 (h 3492)
NGC 5264 (h 3528)
NGC 5408 (h 3553)
IC 4247 (Frost 1042 - Ann. Har. 60 (1908))
IC 4316 (Frost 1083 - Ann. Har. 60 (1908))
ESO 381-20 (MCG-6-28-017; 1243-33)
ESO 324-24 (MCG-6-30-003; 1324-41)
ESO 444-84 (MCG-5-32-000; 1334-27)
ESO 325-11 (1342-41)
ESO 383-87 (MCG-6-30-025; 1346-35)

Near or on the edge of this group, thus possibly further, outlying members are:

NGC 5068: At approximately the same distance, but 20 deg north of the group's center (corresponding to a distance of about 3 million ly) or half
Circinus Galaxy (ESO 97-13): At a similar distance, but about 22 deg south of Centaurus A (again about 3 million ly)
