A polarization survey of over 200 young stars near the Orion Nebula indicates that 25 percent of the sample shows linear polarization significantly above the average interstellar value for this cluster. Several regions of high polarization and reddening exist in the Orion cluster, although not all the stars in these regions are highly polarized. Position angles of polarization are not randomly distributed, which suggests that an external polarization mechanism operates for most of the polarized stars. Polarization is always accompanied by the presence of infrared excesses. Finally, the amounts and origins of polarization are considered as a function of stellar spectral type and color.
