We report the discovery of a parsec-scale Herbig-Haro flow emanating from the young binary system Haro 6-10 in Taurus. The flow extends for about 39' (1.6 pc) at a position angle of about 222 deg and contains part of the previously known HH 184. The apparent ends of the flow are defined by the newly discovered HH 410 and HH 411, which are located 24' southwest and 15' northeast, respectively, from Haro 6-10. We suggest that the giant HH flow is most likely driven by the infrared companion to the T-Tauri primary in Haro 6-10 however, the T-Tauri component also appears to be driving a relatively weak and much smaller outflow with a north-south orientation. The two flows appear to undergo synchronized episodes of increased mass ejection, which may be due to enhanced gravitational interactions between the binary components during periastron. We also report the discovery of a new HH jet, HH 414, which is driven by IRAS 04264+2433. HH 414 points directly toward an associated bow shock, HH 413; the HH 413/414 flow crosses the axis of the HH 410/411 flow at a large angle.
