Triggered star formation occurs when the collapse of an interstellar molecular cloud to form new stars is instigated by external forces.

The process of how stars form is a topic of active research in astronomy. A large fraction of stars are born large star-formation complexes, which may birth tens to hundreds of thousands of young stars. Several examples of such complexes in our Milky Way Galaxy include the Orion Molecular Clouds (containing the Orion Nebula, the Flame Nebula, and the Horsehead Nebula) and the Carina Nebula (containing Trumpler 14, Trumpler 15, Trumpler 16, and the Treasure Chest. In these complex environments, interaction between young stars and the interstellar clouds of gas (molecular clouds) from which they form can significantly affect the star-birth process—a phenomenon known as feedback.
