The 6th Ring Road (Chinese: 六环路; pinyin: Liùhuán Lù) is an expressway ring road in Beijing, China, which runs around the city approximately 15–20 kilometres (9.3–12.4 mi) from the center of the city.

By 2002, a road section starting in Xishatun (interchange with the Badaling Expressway) through to Sanhui Bridge, as well as a stretch from Majuqiao through to Huangcun/Shuangyuan Bridge (interchange with the Jingkai Expressway), were complete and opened to the general public.

In the first case, the expressway was opened on December 20, 2004, at 14:00 local time, with over a month's delay.

To re-connect several break-of-roads in MC region, Beijing Municipality government decided in 2019 that part of eastern 6th Ring, approximately 16 km, will be widen from 4-lane bidirectional to 6-lane, of which the middle 9.2km section will renovate as an underground section.

In September 2020, the biggest tunnel boring machine in China has built in Changsha to join the renovation works.

There have been (a few) calls to eradicate all toll gates within the confines of, and including, the 6th Ring Road.

The 6th Ring Road is linked with Jingshi, Jingcheng, and Jingkai Expressways toll systems.

Although, strictly speaking, it is still on the perimeters of city limits, this is one massive ring road for a motorist to travel around.
