NGC 3054 is an intermediate spiral galaxy in the constellation Hydra. Its velocity with respect to the cosmic microwave background is 2,758±24 km/s, which corresponds to a Hubble distance of 132.7 ± 9.4 Mly (40.68 ± 2.87 Mpc). However, 21 non-redshift measurements give a closer mean distance of 96.98 ± 6.35 Mly (29.733 ± 1.946 Mpc). It was discovered by German–American astronomer Christian Peters on 3 April 1859.
