Over 80 supernova remnants are now known in the Large and Small Magellanic Clouds, where they form an ideal sample for study with Chandra and Spitzer. This sample can be used to constrain cosmic-ray electron acceleration in shocks, using upper limits to nonthermal X-ray emission; to type supernovae from the composition of their ejecta, using thermal X-ray spectroscopy; to identify dynamical characteristics, using X-ray morphology and spectra; to study formation and destruction of dust, using infrared imaging; and to study pulsar-wind nebulae, using observations at all bands. I shall give examples of each of these applications, with particular attention to recent Spitzer data indicating substantial destruction of small grains in remnant shock waves.
