We present initial results of a program to determine the properties of Planetary Nebulae (PNe) in the Spitzer SAGE survey of the Large Magellanic Cloud (LMC). We have constructed IRAC mosaics of a sample of previously identified PNe in the LMC. Of the 233 PNe in the SAGE survey area, we found 213 that had IRAC sources within 1.5 arcsec of the catalog positions, and 118 had detections in all four IRAC bands. The IRAC colors of the PNe span a similar range as a sample of Galactic PNe. IRS spectra of the LMC PNe reveal several classes of spectral types, including ones dominated by warm dust continuum, PAH features, or emission lines from the ionized gas, including [Ne VI] at 7.65 microns. Several of the PNe are resolved with IRAC, and we compare the images to previous HST imaging at optical wavelengths. We present color-color plots and IRAC images of the detected PNe.
