Interstate 485 (I-485), also known as the Charlotte Outerbelt, is a 66.68-mile-long (107.31 km) auxiliary Interstate Highway encircling Charlotte, North Carolina. As a complete loop, it is primarily signed with "inner" and "outer" designations, though at some major interchanges, supplemental signage reflects the local compass orientation of the road. The entire route lies within Mecklenburg County.

A beltway for the Charlotte metropolitan area was first proposed in the mid-1970s, with the first section opening in 1990. The beltway was completed in stages over the next several decades, including the completion of the last segment of the highway on June 5, 2015.
