NGC 4273 is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2,727±24 km/s, which corresponds to a Hubble distance of 131.2 ± 9.3 Mly (40.23 ± 2.84 Mpc). However, 20 non-redshift measurements give a much closer distance of 94.72 ± 4.68 Mly (29.040 ± 1.435 Mpc). It was discovered by German-British astronomer William Herschel on 17 April 1786.

According to A.M. Garcia, NGC 4273 is a member of the NGC 4235 [fr] group (also known as LGG 281). This galaxy group contains at least 29 members, of which 18 appear in the New General Catalogue and 4 in the Index Catalogue.
