NGC 4619 is a barred spiral galaxy in the constellation of Canes Venatici. Its velocity with respect to the cosmic microwave background is 7,176±18 km/s, which corresponds to a Hubble distance of 345.2 ± 24.2 Mly (105.84 ± 7.41 Mpc). However, 15 non-redshift measurements give a closer mean distance of 331.74 ± 12.34 Mly (101.713 ± 3.783 Mpc). It was discovered by German-British astronomer William Herschel on 1 May 1785.

NGC 4619 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.
