The XMM-Newton satellite has given a strong new impetus to the investigation of stellar coronae. It carries high-resolution X-ray spectroscopic instruments that give access to information on the physical conditions in coronal plasmas. Furthermore, its sensitive imaging detectors produce high-quality X-ray images with a large field of view. I will review results on stellar coronae obtained with XMM-Newton: among other topics, I will discuss the elemental composition of stellar coronae and plasma electron densities in quiescence and during flares. I will present evidence for various signatures of the Neupert effect in stars, which provides evidence of chromospheric and coronal heating by flares. Coronal structures based on eclipse mapping inferred from light curve inversion will be shown.
