NGC 7619 is an elliptical galaxy located in the constellation Pegasus. NGC 7619 and NGC 7626 are the dominant and brightest members of the Pegasus galaxy cluster. Both of them were discovered by William Herschel on September 26, 1785.{{cite web|url=http://cseligman.com/text/atlas/ngc76.htm#7619|title=New General Catalogue objects: NGC 7600 - 7649|author=Seligman, Courtney|website=cseligman.com|accessdate=2021-02-10}}

The radial velocity of this galaxy was measured in 1929 and found to be double that of any galaxy observed at that time. The measurement was consistent with the extrapolated value predicted by Edwin Hubble; a distance-velocity relation that would later become known as Hubble's law.

One supernova has been observed in NGC 7619: SN 1970J (type Ia, mag. 14.5) was discovered by Leonida Rosino on 24 September 1970.{{cite web | website=Transient Name Server | title=SN{{nbsp}}1970J | url=https://www.wis-tns.org/object/1970J | publisher = IAU | access-date=2 December 2024}}{{cite simbad|title= SN 1970J|accessdate=2021-02-10}}
