NGC 7714 is a spiral galaxy in the constellation Pisces. Its velocity with respect to the cosmic microwave background is 2430 ± 26 km/s, which corresponds to a Hubble distance of 116.9 ± 8.3 Mly (35.85 ± 2.54 Mpc).^[2] In addition, five non-redshift measurements give a distance of 92.24 ± 8.69 Mly (28.280 ± 2.664 Mpc).^[5] It was discovered by British astronomer John Herschel on 18 September 1830.^[6]

NGC 7714 and NGC 7715 are interacting galaxies.^[4] The pair are included in Halton Arp's Atlas of Peculiar Galaxies, listed as Arp 284.^[7] NGC 7714 appears to be a highly distorted spiral, possibly a barred spiral galaxy. NGC 7715 is of uncertain type, probably an edge-on spiral or an irregular galaxy.^[3]

Three supernovae have been observed in NGC 7714:

SN 1999dn (type Ib/c, mag. 16.3) was discovered by the BAO Supernova Survey on 19 August 1999.^[8]^[3]^[9]
SN 2007fo (type Ib/c, mag. 18.2) was discovered by the Lick Observatory Supernova Search on 9 July 2007.^[10]^[11]
SN 2023pso (type Ib, mag. 17.1) was discovered by GOTO on 7 August 2023.^[12]
