NGC 514 is a low-luminosity,[8] intermediate spiral galaxy in the equatorial constellation of Pisces, located at a distance of approximately 83[3] million light-years from the Milky Way. It was discovered on 16 October 1784 by astronomer William Herschel.[9] The general form of the galaxy is specified by its morphological classification of SAB(rs)c,[5] which indicates it has a weak bar system at the core (SAB), an incomplete ring formation around the bar (rs), and somewhat loosely-wound spiral arms (c). This galaxy has an H II nucleus[10] with an extended region that displays weak emission lines in the optical range, but not in the near infrared.[5] The suspected supermassive black hole at the core has an estimated mass of 3.2×106 M☉.[8]

In October 2020 a type Ia supernova, SN 2020uxz, was detected in NGC 514.[11][12]
