NGC 4414 is an unbarred spiral galaxy about 62 million light-years away in the constellation Coma Berenices. It is a flocculent galaxy, with short segments of spiral structure but without the dramatic well-defined spiral arms of a grand design spiral. In 1974 a supernova, SN 1974G, was observed and is the only supernova in NGC 4414 to be recorded so far.

NGC 4414 was imaged by the Hubble Space Telescope in 1995, as part of the HST's main mission to determine the distance to galaxies, and again in 1999 as part of the Hubble Heritage project. It has been part of an ongoing effort to study its Cepheid variable stars.

The outer arms appear blue due to the continuing formation of young stars. The galaxy's arms are also rich in interstellar dust which appear as patches and streaks silhouetted by the starlight.
