List of star-forming regions in the Local Group

{{short description|Regions in the Milky Way galaxy and Local Group where new stars are forming}}

This is a list of star-forming regions located in the Milky Way Galaxy and in the Local Group. Star formation occurs in molecular clouds which become unstable to gravitational collapse, and these complexes may contain clusters of young stars and regions of ionized gas called H II regions. Stars typically form in groups of many stars, rather than in isolation.
