IC 2560 is a spiral galaxy lying over 110 million light-years away from Earth in the constellation of Antlia. It was discovered by Lewis Swift on 28 December 1897.

The luminosity class of IC 2560 is II with a broad HI line containing regions of ionized hydrogen. Moreover, IC 2560 is an active Type 2 Seyfert Galaxy. It has a distinct bar structure in the center with the supermassive black hole at the core having a mass of 4.4+4.4
−2.2×106 M☉.

One supernova has been observed in IC 2560. SN 2020ejm (Type Ia, mag. 16) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 11 March 2020.
