NGC 2535 is an unbarred spiral galaxy in the constellation Cancer. It was discovered on 22 January 1877 by French astronomer Édouard Stephan.[2]

NGC 2535 is exhibiting a weak inner ring structure around the nucleus that is interacting with NGC 2536. The interaction has warped the disk and spiral arms of NGC 2535, producing an elongated structure, visible at ultraviolet wavelengths, that contain many bright, recently formed blue star clusters in addition to enhanced star forming regions around the galaxy center. The two galaxies are listed together as Arp 82 in the Atlas of Peculiar Galaxies as an example of a spiral galaxy with a high surface brightness companion.[3]

One supernova has been observed in NGC 2535. SN 1901A (type unknown, mag. 14.7)[4][5] was seen by Karl Reinmuth on a photographic plate taken on 10 January 1901, although the discovery was not made until 28 September 1923.[6][7]
