The Norma Cluster (ACO 3627 or Abell 3627) is a rich cluster of galaxies located near the center of the Great Attractor; it is about {{convert|68|Mpc|Mly|0|abbr=on|lk=on}} distant.[https://arxiv.org/abs/astro-ph/0006199 R.

| access-date=2012-02-25}} Although it is both nearby and bright, it is difficult to observe because it is located in the Zone of Avoidance, a region near the plane of the Milky Way. Consequently, the cluster is severely obscured by interstellar dust at optical wavelengths. Its mass is estimated to be on the order of 10¹⁵ solar masses.

ESO 137-001, an example of a jellyfish galaxy, is located in Abell 3627.{{cite web |title=New Hubble image of spiral galaxy ESO 137-001 |url=https://www.spacetelescope.org/images/heic1404a/ |website=www.spacetelescope.org |language=en}}
