We present maps of the Lupus molecular cloud complex at 24, 70, and 160 microns using the Spitzer Space Telescope. These clouds were observed as part of the Spitzer Legacy Science Program, ``From Molecular Cores to Planet-Forming Disks'' (Evans et al. 2003). Utilizing the 2MASS catalog in addition to the Spitzer wavelengths, we made K vs. K-[24] and [24] vs. [24]-[70] color-magnitude diagrams. Significant background galaxy contamination exists among those objects with positive K-[24] and [24]-[70] colors. We used SWIRE observations of the Elais N1 region to separate candidate young stellar objects from background galaxies. Some of these YSO candidates are discussed individually.
Support for this work, utilizing data from the ``Cores to Disks'' Spitzer Legacy Science Program, was provided by NASA through contract 1224608 issued by the Jet Propulsion Laboratory, California Institute of Technology, under NASA contract 1407.
