The Xinhua News Agency (simplified Chinese: 新华通讯社; traditional Chinese: 新華通訊社; pinyin: Xīnhuá tōngxùnshè, IPA: [ɕínxwǎ]; /ˈʃiːnhwɑː/; literally "New China News Agency") is the official press agency of the People's Republic of China and the biggest center for collecting information and press conferences in China. It is the largest news agency in China, ahead of the China News Service. Xinhua is subordinate to the State Council and reports to the Communist Party of China's Publicity and Public Information Departments. Xinhua's headquarters complex, the "pencil building", is at No. 57 Xuanwumenxi Street, Beijing. Its website Xinhua.org or Xinhuanet.com is headquartered on the twentieth floor of the Dacheng Plaza (大成大厦 Dàchéng Dàshà) in Xicheng District, Beijing.

Xinhua employs more than 10,000 people, operates 107 foreign bureaus worldwide, and maintains 31 bureaus in China—one for each province, plus a military bureau. As most of the newspapers in China cannot afford to station correspondents abroad, or even in every Chinese province, they rely on Xinhua feeds to fill their pages. People's Daily, for example, uses Xinhua material for approximately 25 percent of its stories. Xinhua is a publisher as well as a news agency—it owns more than 20 newspapers and a dozen magazines, and it prints in eight languages: Chinese, English, Spanish, French, Russian, Portuguese, Arabic and Japanese.

A news agency is an organization of journalists established to supply news reports to news organizations: newspapers, magazines, and radio and television broadcasters. Such an agency may also be referred to as a wire service, newswire, or news service.

The oldest news agency is Agence France-Presse (AFP). It was founded in 1835 by a Parisian translator and advertising agent, Charles-Louis Havas as Agence Havas. Two of his employees, Paul Julius Reuter and Bernhard Wolff, later set up rival news agencies in London and Berlin respectively. In 1853, in Turin, Guglielmo Stefani founded the Agenzia Stefani, that became the most important agency in the Kingdom of Italy, and took international relevance with Manlio Morgagni.

In order to reduce overhead and develop the lucrative advertising side of the business, Havas's sons, who had succeeded him in 1852, signed agreements with Reuter and Wolff, giving each news agency an exclusive reporting zone in different parts of Europe.

News agencies can be corporations that sell news (e.g. Press Association, Thomson Reuters and United Press International). Other agencies work cooperatively with large media companies, generating their news centrally and sharing local news stories the major news agencies may chose to pick up and redistribute (i.e. AP, Agence France-Presse (AFP) or American Press Agency (APA)). Commercial newswire services charge businesses to distribute their news (e.g. Business Wire, the Hugin Group, GlobeNewswire, Marketwire, PR Newswire, CisionWire, and ABN Newswire). Governments may also control news agencies: China (Xinhua), Canada^{[citation needed]}, Russia (ITAR-TASS) and other countries also have government-funded news agencies which also use information from other agencies as well.
