We characterize the SWIRE galaxy populations in the SWIRE validation fieldwithin the Lockman Hole, based on the 3.6-24$\mu$ Spitzer data and deepU,g',r',r' optical imaging within an area ~1/3 sq. deg for ~16,000Spitzer-SWIRE sources. The entire SWIRE survey will discover over 2.3 milliongalaxies at 3.6$\mu$m and almost 350,000 at 24$\mu$m; ~70,000 of these will be5-band 3.6-24$\mu$ detections. The colors cover a broad range, generally wellrepresented by redshifted spectral energy distributions of known galaxypopulations, however significant samples of unusually blue objects in the[3.6-4.5]$\mu$m color are found, as well as many objects very red in the3.6-24$\mu$m mid-IR. Nine of these are investigated and are interpreted asstar-forming systems, starbursts and AGN from z=0.37 to 2.8, with luminositiesfrom L$_{IR}$=10$^{10.3}$ to 10$^{13.7}$ L$_{\odot}$Comment: Accepted for publication in the ApJ Supplements Spitzer Special Issue 17 pages, 4 figure
