We present initial results and source lists of variable sources in the LargeMagellanic Cloud (LMC) for which we detect thermal infrared variability fromthe SAGE (Surveying the Agents of a Galaxy's Evolution) survey, which had 2epochs of photometry separated by three months. The SAGE survey mapped a 7degree by 7 degree region of the LMC using the IRAC and the MIPS instruments onboard Spitzer. Variable sources are identified using a combination of the IRAC3.6, 4.5, 5.8, 8.0 \micron bands and the MIPS 24 \micron bands. Anerror-weighted flux difference between the two epochs is used to assess thevariability. Of the ~ 3 million sources detected at both epochs we find ~ 2,000variable sources for which we provide electronic catalogs. Most of the variablesources can be classified as asymptotic giant branch (AGB) stars. A largefraction (> 66%) of the extreme AGB stars are variable and only smallerfractions of carbon-rich (6.1%) and oxygen-rich (2.0%) stars are detected asvariable. We also detect a population of variable young stellar objectcandidates.
