NGC 4273 is a barred spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is 2727 ± 24 km/s, which corresponds to a Hubble distance of 131.2 ± 9.3 Mly (40.23 ± 2.84 Mpc).[1] However, 20 non-redshift measurements give a distance of 94.72 ± 4.68 Mly (29.040 ± 1.435 Mpc).[2] It was discovered by German-British astronomer William Herschel on 17 April 1786.[3]

According to A.M. Garcia, NGC 4273 is one of the galaxies in the NGC 4235 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.[4]
