NGC 4168 is an elliptical galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background is , which corresponds to a Hubble distance of . However, 13 non-redshift measurements give a closer mean distance of . It was discovered by German-British astronomer William Herschel on 8 April 1784.
NGC 4168 is a Seyfert II galaxy, i.e. it has a quasar-like nucleus with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable.
Virgo cluster NGC 4168 is a member of the Virgo Cluster.
Supernova One supernova has been observed in NGC 4168: SN 2026acd (TypeIa, mag. 18.876) was discovered by ATLAS on 14 January 2026.
