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 in 1897.[3]

The luminosity class of IC 2560 is II[4] with a broad HI line[5] containing regions of ionized hydrogen. Moreover, IC 2560 is an active Type 2 Seyfert Galaxy.[6] 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☉.[7]

One supernova, SN 2020ejm (type Ia, mag. 16), was discovered in IC 2560 on 11 March, 2020.[8]
