The Orion region is the closest site of recent OB star formation, containing much interstellar gas and dust in a variety of physical conditions. This region is well suited for study of dust extinction and emission. The DIRBE instrument aboard the COBE(1) spacecraft provides a new opportunity to gain insights into the properties of interstellar dust grains and the energetics of this star-forming region. As part of its all-sky survey, DIRBE has observed the entire Orion region in 10 wavelength bands spanning the infrared spectrum from 1 to 240microns . This broad spectral range allows studies of dust extinction, stellar emission, hot and cold dust emission, and permits reliable estimates of the bolometric luminosity of the region. Preliminary DIRBE broad-band spectral energy distributions are presented for the Orion complex, along with spectral decomposition results. {\sevenrm {\refindent (1) COBE is supported by NASA's Astrophysics Division Goddard Space Flight Center (GSFC), under the scientific guidance of the COBE Science Working Group, is responsible for the development and operation of COBE.}}
