NGC 275 is a barred spiral galaxy located approximately 63 million light-years from the Solar System[2] in the constellation Cetus. It is one of a pair of galaxies, the other being NGC 274. It was discovered on October 9, 1828, by John Herschel.[3]

The galaxy was described as "very faint, small, round, southeastern of 2" by John Dreyer in the New General Catalogue, with the other of the two galaxies being NGC 274.[3]

It is part of a galaxy group known as LGG 15 or NGC 274 Group. It has at least 3 members, which are NGC 274, NGC 298 and NGC 337.[4]
