The Beijing–Taipei Expressway (Chinese: 北京–台北高速公路; pinyin: Běijīng–Táiběi Gāosù Gōnglù), designated as G3 and commonly known as the Jingtai Expressway (Chinese: 京台高速公路; pinyin: Jīngtái Gāosù Gōnglù), is a partially completed Chinese expressway that, if fully constructed, would connect the People's Republic of China with Taiwan.

The project has been the source of some controversy because of Taiwan's political status.

The People's Republic of China claims Taiwan, but has never administered it, so therefore does not have any control of its highways.

Aside from politics, the other challenge is the engineering difficulties in constructing the link through the Taiwan Strait.

In China, it connects the cities of Beijing, Langfang, Cangzhou, Dezhou, Jinan, Tai'an, Xuzhou, Bengbu, Hefei, Tongling, Huangshan, Quzhou, and Fuzhou.
