NGC 515, also occasionally referred to as PGC 5201 or UGC 956, is a lenticular galaxy located approximately 228 million light-years from the Solar System[4] in the constellation Pisces.

The position noted for NGC 515 is just 35 seconds east of UGC 956, thus the two entries are generally thought to be the same object.

[6] The object was also observed by John Herschel, son of William Herschel and later catalogued by John Louis Emil Dreyer in the New General Catalogue, where the galaxy was described as "pretty faint, very small, round, northwestern of 2" with the other one being NGC 517.

[5] The galaxy has an apparent visual magnitude of 13.1 and can be classified as type S0 using the Hubble Sequence.

[2] The object's distance of roughly 230 million light-years from the Solar System can be estimated using its redshift and Hubble's law.
