NGC 4323 is a lenticular or dwarf elliptical galaxy located about 52.5 million light-years away in the constellation Coma Berenices. The galaxy was discovered in 1882 by astronomer Wilhelm Tempel and is a member of the Virgo Cluster. NGC 4323 is commonly misidentified as NGC 4322, which is a 13th magnitude star.

Interaction with Messier 100

NGC 4323 is a companion of Messier 100, which lies 24 kpc away. The two galaxies appear to be interacting, as evidenced by Messier 100's rotation curve, an asymmetry of its HI disk, and a faint, optical bridge that connects it to NGC 4323. However, Knapen et al. suggests that the two galaxies are not interacting as NGC 4323 is a small galaxy and has a large separation from Messier 100.
