UGC 3478 is a spiral galaxy located in the constellation of Camelopardalis. Its velocity with respect to the cosmic microwave background is 3,849±8 km/s, which corresponds to a Hubble distance of 185.2 ± 13.0 Mly (56.77 ± 3.98 Mpc). However, three non-redshift measurements give a closer mean distance of 142.10 ± 1.71 Mly (43.567 ± 0.524 Mpc). The first known reference to this galaxy comes from Part 1 of the Morphological Catalogue of Galaxies, published in 1962, where it is listed as MCG +11-08-054.

UGC 3478 features a growing supermassive black hole (AGN) at its center.
