We have performed a deep [SII]6717/6731 wide field Herbig-Haro (HH) objectsurvey toward the Vela C molecular cloud with a sky coverage of about 2 deg2.In total, 18 new HH objects, HH 1090-1107, are discovered and the twopreviously known HH objects, HH 73-74, are also detected in our [SII] images.We also present an investigation of mid-infrared outflows in the Vela Cmolecular cloud using the Wide-field Infrared Survey Explorer images taken fromAllWISE data release. Using the method suggested by Zhang & Wang, elevenextended green objects (EGOs) are identified to be the mid-infrared outflows,including 6 new mid-infrared outflows that have not been detected previously atother wavelengths and 5 mid-infrared counterparts of the HH objects detected inthis work. Using the AllWISE Source Catalog and the source classificationscheme suggested by Koenig et al., we have identified 56 young stellar object(YSO) candidates in the Vela C molecular cloud. The possible driving sources ofthe HH objects and EGOs are discussed based on the morphology of HH objects andEGOs and the locations of HH objects, EGOs and YSO candidates. Finally weassociate 12 HH objects and five EGOs with 10 YSOs and YSO candidates. Themedian length of the outflows in Vela C is 0.35pc and the outflows seem to beoriented randomly.
