The Politics of Xi'an in Shaanxi province in the People's Republic of China is structured in a dual party-government system like all other governing institutions in mainland China.
The Mayor of Xi'an is the highest-ranking official in the People's Government of Xi'an or Xi'an Municipal Government. However, in the city's dual party-government governing system, the Mayor has less power than the Communist Party of Xi'an Municipal Committee Secretary, colloquially termed the "CPC Party Chief of Xi'an" or "Communist Party Secretary of Xi'an".
