Supernova remnants (SNRs) are important laboratories for the study of a
variety of astrophysically important processes, including shock
interactions between the expanding remnant and the interstellar medium and
the condensation of dust in chemically enriched ejecta. Infrared (IR)
observations are crucial for the study of the dust content and grain
processing and for determination of grain properties and elemental
abundances in SNRs. The imaging and spectroscopic instruments on the
Spitzer Space Telescope have provided a unique opportunity to study the
composition and spatial morphology of SN ejecta and dust in SNRs. Recent
Spitzer observations of SNRs are reviewed, including observations of the
Crab and Cas A, spectroscopic monitoring of SN 1987A, and large surveys of global characteristics of SNRs in the IR. The role of IR observations in
addressing future challenges and opportunities for progress in SNR
research will also be discussed.
