List of nearby stellar associations and moving groups

This is a list of nearby stellar associations and moving groups. A stellar association is a very loose star cluster, looser than an open cluster. A moving group is the remnant of such a stellar association. Members of stellar associations and moving groups share similar kinematic properties, as well as similar ages and chemical composition.

This list is incomplete; you can help by adding missing items with reliable sources.

The list is sorted after the distance to the solar system.
