Jingjintang Expressway (Chinese: 京津塘高速公路; pinyin: Jīngjīntáng Gāosùgōnglù), also known as the Jingtang Expressway, links Beijing via central Tianjin to the Tanggu District in eastern Tianjin. 143 kilometres in length, it crosses the jurisdictions of Beijing and Tianjin municipalities and Hebei province.

Tolls apply as of Dayangfang near the Eastern 5th Ring Road in Beijing until the Tanggu/TEDA exit. The expressway uses a networked toll system across all jurisdictions and is managed by Huabei (North China) Expressways.

This route is now part of G2 Beijing–Shanghai Expressway and Tianjin () expressway.

The Jingjintang Expressway runs through the municipalities of Beijing and Tianjin, as well as Hebei province.

Beijing (Fenzhongsi - Shibalidian - Dayangfang - Majuqiao - Caiyu) - Langfang (Hebei) - Tianjin (Yangcun - Central Tianjin - Tianjin Airport - Tanggu District/TEDA).

The expressway opened on September 25, 1993, and was the first expressway to be built to more recent standards.

This expressway has slashed driving time from Beijing to Tianjin to around one hour, and has created a corridor between Beijing and Tianjin.

Areas of the expressway are many times very foggy and that has led to a number of accidents.
