Hanzhong Chenggu Airport, or Chenggu Air Base, is a dual-use military and civil airport serving the city of Hanzhong in Shaanxi province, China. Located in Chenggu County northeast of Hanzhong, it replaced the old Hanzhong Xiguan Airport, which could not be expanded due to its proximity to the city center. Construction commenced in late December 2011 with an estimated total investment of 580 million yuan, and the airport was opened on 13 August 2014.
