NGC 3281 is a large unbarred spiral galaxy[5] in the southern constellation of Antlia, located at a distance of 144.7 megalight-years[2] from the Milky Way. The galaxy is inclined by an angle of 64° to the line-of-sight from the Earth, with the major axis aligned with a position angle of 137°.[6] It is a luminous infrared galaxy and a type II Seyfert galaxy.[7] NGC 3281 is a member of the Antlia Cluster,[3] which belongs to the Hydra–Centaurus Supercluster.
