NGC 5260 is a barred spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 6789 ± 21 km/s, which corresponds to a Hubble distance of 100.13 ± 7.02 Mpc (∼327 million light-years). It was discovered by American astronomer Lewis Swift on 6 April 1885.

According to the SIMBAD database, NGC 5260 is a Seyfert II galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.

NGC 5260 forms a physical pair with galaxy ESO 509- G 093, collectively named RR 254, with an optical separation of 241″ between them.
