NGC 7714 is a spiral galaxy in the constellation Pisces. It was discovered by John Herschel on 18 September 1830.

NGC 7714 and NGC 7715 are interacting galaxies.[3] The pair are also known as Arp 284. 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.[2]

Three supernovae have been observed in NGC 7714: SN 1999dn (type Ib/c, mag. 16.3),[2][4] SN 2007fo (type Ib/c, mag. 18.2),[5] and SN 2023pso (type Ib, mag. 17.1).[6]
