NGC 7124 is a large spiral galaxy in the constellation of Indus. Its velocity with respect to the cosmic microwave background is 4988 ± 15km/s, which corresponds to a Hubble distance of 240.0 ± 16.8 Mly (73.57 ± 5.16 Mpc). However, nine non-redshift measurements give a much closer distance of 191.56 ± 4.26 Mly (58.733 ± 1.306 Mpc). It was discovered by British astronomer John Herschel on 8 July 1834.

NGC 7124 is classified as a LINER galaxy, i.e. it has a type of nucleus that is defined by its spectral line emission which has weakly ionized or neutral atoms, while the spectral line emission from strongly ionized atoms is relatively weak.

One supernova has been observed in NGC 7124: SN 2023pwl (Type Ia, mag. 16.728) was discovered by ATLAS on 19 August 2023.
