U.S. Route 29 is a north–south United States highway that runs for 168 miles (270 km) from the South Carolina state line, near Blacksburg, to the commonwealth of Virginia, near Danville. The route serves the North Carolina Piedmont, including the cities of Charlotte, Salisbury, High Point, and Greensboro.

Established in 1927, it ran from the South Carolina state line to US 74 in Kings Mountain, with a concurrency with NC 205. In 1929, NC 205 was removed.

US 29's first extension was in 1932, following US 74/NC 20 east into Charlotte; it then replaced US 170 from Charlotte to the Virginia state line. In 1937, it replaced a stretch of NC 7 going between Kings Mountain and Gastonia; the old route briefly became alternates for both U.S. Routes before becoming NC 161 and NC 274.
