Supernova remnants (SNRs) are the fingerprints left in the interstellar medium by either thermonuclear (type Ia) or core-collapse (CC) supernova explosions. The Magellanic Clouds (MCs) offer an ideal laboratory for the study of SNR populations in star-forming galaxies. Both the Large and Small Magellanic Clouds have been targeted by large XMM-Newton surveys, which, combined with archival observations, provide the best dataset to systematically study the X-ray emission of the numerous SNRs they host. These sources can be homogeneously studied in detail from the youngest (SN1987A) to the most evolved stages. SNRs are then be used as probes of their host galaxies, to e.g. measure abundances in the gas phase of the MCs and provide clues to their past star formation history. Finally, the issue of observationally typing SNRs will be presented, with the implications for the core-collapse progenitor mass distribution and the origin of type Ia supernova discussed.
