I am presenting my search for variable stars in the Small Magellanic Cloud (SMC) using the observations made by the Spitzer SAGE-SMC Legacy program. Three epochs of data were used, two of which taken 3 months apart and one taken three years before. Each epoch was taken using two infrared imaging instruments on the Spitzer Space Telescope: the Infrared Array Camera (IRAC) and the Multiband Imaging Photometer for Spitzer. I found 825 sources that meet the variability criteria defined: a source must have |Vband| > 3 in at least two neighboring bands in the same direction. These sources were, then, plotted on color magnitude diagrams for classifying. 57 sources have been visually verified as variable out of the 80 sources checked. Thanks to the National Science Foundation and the University of Toledo for their support.
