NGC 5915 is a barred spiral galaxy in the constellation of Libra. Its velocity with respect to the cosmic microwave background is 2449 ± 13 km/s, which corresponds to a Hubble distance of 36.12 ± 2.54 Mpc (∼118 million light-years). It was discovered by British astronomer John Herschel on 5 June 1836.

NGC 5915 forms a galaxy triplet due to gravitational interactions with NGC 5916 and NGC 5916A (also known as PGC 54779).

One supernova has been observed in NGC 5915: SN 2023cpt (type Ic, mag 17.1) was discovered by ATLAS on 27 February 2023.
