NGC 2841 is an inclined unbarred spiral galaxy exhibiting a prominent inner ring structure in the constellation Ursa Major, it was discovered on 9 March 1788 by William Herschel. Initially thought to be about 30 million light years distant, a 2001 Hubble Space Telescope survey of the galaxy's Cepheid variables determined that it was approximately 14.1 megaparsecs or 46 million light years distant.

NGC 2841 is a giant spiral galaxy with properties similar to those of the Andromeda Galaxy. It is a prototypical flocculent spiral galaxy, a type of spiral galaxy whose arms are patchy and discontinuous.

NGC 2841 is home to large population of young blue stars, and few H II regions.

NGC 2841 contains a low-ionization nuclear emission-line region (LINER), a type of region that is characterized by spectral line emission from weakly ionized atoms.
