We present mid-infrared images (5--40 micron) of the central portion of the W40 star forming region using the FORCAST instrument on SOFIA. These data were obtained as part of the SOFIA Basic Science Guest Investigator program during the summer of 2011, and are the highest resolution images of this region in the 20--40 micron wavelength range to date. Our images reveal a handful of protostellar sources in addition to diffuse emission from warm dust in the background nebula. We combine the SOFIA results with ground based photometry and spectroscopy to generate full optical/near-IR to mid-IR spectral energy distributions for the sources detected and compare them to standard models for young stellar objects of various masses and ages. We also discuss the nature of the mid-IR emission for IRS 3A, an early-B star that appears to be located within a small cocoon of warm dust.
