NGC 2930 is a spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 7,674±25 km/s, which corresponds to a Hubble distance of 369.2 ± 25.9 Mly (113.19 ± 7.93 Mpc). However, 12 non-redshift measurements give a closer mean distance of 314.44 ± 19.25 Mly (96.408 ± 5.901 Mpc). It was discovered by German astronomer Heinrich Louis d'Arrest on 21 February 1863.
