The Spitzer Space Telescope is continuing to contribute greatly to our understanding of the mass return from evolved stars in the Magellanic Clouds (MCs). I first review a number of smaller early Spitzer studies of evolved stars in the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC). These studies often built upon earlier such studies using data from prior missions, like the Midcourse Space Experiment. I discuss various Spitzer spectroscopic studies that have investigated the dust compositions of evolved stars in the lower metallicity environments of the MCs. Also, I review studies of the MCs' massive evolved stars, which have been given somewhat less attention than other populations. Excitingly, using Spitzer data, for the first time the mass-loss from the diverse evolved star MC populations is being quantified. With the advent of the Surveying the Agents of a Galaxy's Evolution (SAGE; PI: M. Meixner) Spitzer Legacy program, tens of thousands of stars in the LMC have been classified as evolved stars using SAGE Spitzer data. I briefly review how evolved stars are classified (e.g., by using color-magnitude and color-color diagrams) using data from the SAGE surveys. Finally, I discuss work on radiative transfer (RT) modeling of evolved stars, which follows earlier work estimating their mass-loss using colors or emission in excess of stellar photosphere emission. This RT work starts by seeking acceptable dust properties for RT models of both SAGE Spectral Energy Distributions (SEDs) and SAGE-Spectroscopy (Spitzer Legacy program; PI: F. Kemper) spectra of asymptotic giant branch (AGB) stars. Afterwards, large grids of RT models are constructed to determine mass-loss rates for AGB stars and red supergiants in the SAGE samples of the LMC and, eventually, the SMC.
