North Carolina Highway 218 is a primary state highway in the state of North Carolina. The highway runs east–west from Mint Hill to Polkton.

NC 218 traverses 31.6 miles (50.9 km); starting in Mint Hill, it goes through northern Union County, then ends in Polkton. The entire route is a two-lane rural highway with little traffic, except in Mecklenburg County where farmland is making way to new bedroom communities.

Established as a new primary routing in 1935, it connected the towns of Mint Hill and Polkton. In the early 1940s, it was extended in Polkton when US 74 was rerouted further south from town. In the 1960s, NC 218 was moved onto a new extension of Williams Street in Polkton, leaving Old U.S. 74.
