NGC 1585 is a spiral galaxy in the constellation of Caelum. Its velocity with respect to the cosmic microwave background is 4,635 ± 31 km/s, which corresponds to a Hubble distance of 68.4 ± 4.8 Mpc (∼223 million light-years). It was discovered by British astronomer John Herschel on 1 December 1837.

The SIMBAD database lists NGC 1585 as a Seyfert I Galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.

One supernova has been observed in NGC 1585: SN 2023vio (type Iax [02cx-like], mag. 19.053) was discovered by ATLAS on 17 October 2023.
