Optical polarization maps are presented for the various nebulosities of the HH34 complex in the L1641 dark cloud. The Herbig-Haro object HH34 and its associated optical jet are unpolarized but their source of excitation (HH34-IRS) is the illuminating star of a reflection nebula which envelops the jet and extends as far as HH34. The optical polarization of HH34-IRS suggests that it is surrounded by a circumstellar disc which collimates the outflows in some manner. There is other reflection nebulosity in the region illuminated by a faint star which the author identifies as the optical counterpart of HH34-IRS5. He has also discovered a small bipolar reflection nebula approximately 20 arcsec west of HH34-IRS.
