Zhongshan, Chungshan, or Jhongshan (Chinese: 中山路) is a common name of Chinese roads, usually in honor of Sun Yat-sen, better known in Chinese as "Sun Chungshan (Zhongshan)", who is considered by many to be the "Father of Modern China".

In Chinese cities, "Zhongshan Road" is often one of a city's principal roads. As a result, the road is often very long and divided into numbered sections. In Guangzhou, the Zhongshan Road is separated into eight sections, identified as the First Zhongshan Road to the Eighth Zhongshan Road. In Shanghai, Zhongshan Road stretches around the whole city, the road is divided into numerous sections, identified by a direction and a number, such as the East-1 Zhongshan Road.

In some exceptional cases, a "Zhongshan Road" can have other significance. Zhongshan Road in Shijiazhuang, for example, is named after the Zhongshan state and later commandery, not Sun Yat-sen.

Sun Yat-sen, a leader of the Republican revolution of the early 20th century, was remembered in China with great fervor after his death in 1925, and especially after his Kuomintang party re-unified China in 1928. As a result, numerous monuments were erected in his honor throughout China, and a large number of streets, parks and schools, and even his birth city (Zhongshan, Guangdong) were renamed in his honor.^{[citation needed]}

When the Republic of China government took over Taiwan at the end of World War II, the practice of naming streets and parks after Sun, and erecting monuments in his honor, spread to the island as well.^{[citation needed]}

Between 1928 and 1949, in a move designed to parallel the adulation of Sun, a number of roads and institutions were named "Zhongzheng", after Chiang Kai-shek, also known as "Jiang Zhongzheng", who saw himself as the successor to Sun.^{[citation needed]}

In 1949, the Chinese Communist Party took control in mainland China and founded the People's Republic of China. Over the following years, streets and institutions named "Zhongzheng" were renamed, but Zhongshan Roads were not renamed, and survived "revolutionary" name changes in the Cultural Revolution. A conventional practice developed where no streets would be named after a political leader, except for Sun Yat-sen. In mainland China today, Sun Yat-sen remains the only modern politician commemorated in road names: no Communist leader, such as Mao Zedong or Deng Xiaoping, shares this privilege.^{[citation needed]}

In Taiwan, Zhongshan (more commonly and locally spelled as "Jhongshan" or "Chungshan") Roads are as ubiquitous, if not more, compared to mainland China. In recent years, the administrative merging of neighboring towns have sometimes resulted in duplicate Zhongshan Roads within the same locality, and as a result some such roads have been renamed.^{[citation needed]}
