Interstate 440 (I-440), also known as the Raleigh Beltline, the Cliff Benson Beltline, or locally as The Beltline, is an Interstate Highway in the US state of North Carolina. I-440 is a 16.4-mile-long (26.4 km) partial beltway that nearly encircles central Raleigh. I-440 begins in west Raleigh at an interchange with I-40 as a continuation of U.S. Highway 64 (US 64)/US 1 and traverses a primarily residential area in west Raleigh. The freeway makes a turn toward the east, crossing US 70, Six Forks Road, and Wake Forest Road. US 1 branches north off I-440 at US 401 (Capital Boulevard), becoming US 401/US 1. I-440 turns toward the southeast and follows a brief concurrency with U.S. Highway 64 Business (US 64 Bus.) before intersecting I-87/US 64/US 264. US 64 and I-87 are concurrent with I-440 along the remainder of the road's southwesterly routing. Exit 16 is the last exit on I-440, where I-440 splits to join either I-40 eastbound or I-40 westbound.

The Raleigh Beltline was formed from a number of highway segments, the earliest of which had been in place since 1959. The loop was completed in 1984 under multiple route designations. To avoid confusion along the beltline, I-440 was routed along the entirety of the beltline and shared a concurrency with its parent, I-40, along the loop's southern segment (Tom Bradshaw Freeway). In 2008, the I-440 designation was removed from the section of I-40/US 64 in southeast Raleigh. The highway's original "inner" and "outer" directions were also removed and replaced with east and west directions. The easternmost two miles (3.2 km) of the I-440 was rebuilt in 2015 as part of the larger widening project along I-40 in South Raleigh, while the westernmost four miles (6.4 km), the oldest segment and one which was not up to Interstate standards, was widened and upgraded.
