Star‐forming regions have been observed in X‐rays since the first generation of satellites in the late 70s. They are very rich in magnetically‐controlled X‐ray phenomena: stellar flares and star‐disk interactions in hundreds of T Tauri stars, confined winds in massive stars, etc. More recently, in a few low‐mass stars, X‐ray evidence has been found for accretion shocks. Even if it is not dominant, when it is found the influence of the circumstellar environment on X‐ray emission gives precious clues on the magnetic structure in the vicinity of young stars.
