NGC 1023 is a barred lenticular galaxy in the northern constellation of Perseus. Alternatively, it is known as the Perseus Lenticular Galaxy. Distance measurements vary from 9.3 to 19.7 million parsecs (30 to 64 million light-years), where it is a member of the NGC 1023 group of galaxies in the Local Supercluster. NGC 1023 is included in Halton Arp's Atlas of Peculiar Galaxies, under the category "Galaxies with Nearby Fragments" under the number 135.

NGC 1023 has been estimated to have about 490 globular clusters, consistent with similar early-type galaxies. There is a supermassive black hole at the core with a mass of (4.4±0.5)×10 M☉. The black hole was discovered by analyzing the dynamics of the galaxy.
