蓝岭山行车信道，是美国东部一条著名的山区风景区路线。

蓝岭山行车信道沿阿巴拉契亚山脉之蓝岭山山岭而兴建的行车信道，由东北向西南伸展，横跨美国维珍尼亚州和北卡罗莱纳州。全长469哩（755千米），沿途更开凿岩石成隧道共26条。蓝岭山行车信道最高处是6053呎（1845米）。沿途多是山区风景区，有森林﹑河流﹑瀑布﹑山谷﹑郊野行山径.....等。树木花卉多样化。

在BBC2台的Top Gear第十五季节目中，该节目日前曾说阿尔巴尼亚的某条公路是世界上最好最美的公路。之后观众投书纠正说蓝岭山公路才是世界上最好的公路，该节目便于第7集准备了三辆顶级超跑前往蓝岭山公路，到了之后却发现限速规定低的毫无乐趣，完全与该节目的价值取向相反。

The Blue Ridge Parkway is a National Parkway and All-American Road in the United States, noted for its scenic beauty. The parkway, which is America's longest linear park, runs for 469 miles (755 km) through 29 Virginia and North Carolina counties, mostly along the Blue Ridge, a major mountain chain that is part of the Appalachian Mountains. Its southern terminus is on the boundary between Great Smoky Mountains National Park and the Cherokee Indian Reservation in North Carolina, from which it travels north to Shenandoah National Park in Virginia and offers access to the Skyline Drive. While the two roads join together end-to-end, they are separate and distinct entities, built as two different projects and managed by two different National Park Service units. The Blue Ridge Parkway was built to connect Shenandoah National Park to the Great Smoky Mountains National Park.
