Southmont is an unincorporated community and census-designated place (CDP) in Davidson County, North Carolina, United States.

A village grew up around the crossroads of where the new Winston-Salem Southbound Railway rail line had crossed the road to Lexington.

The school became grades 1-8 and by the early 1960s people began to build summer cottages at High Rock Lake.

During a 1979 bridge repair, Hwy 8 was closed for nearly two years and much of the lake was found to have mercury contamination from a battery plant upstream.

Over the past 10 years the community has again seen a resurgence of growth, with multiple small businesses, a new school, new post office, expanded churches, a new fire station, an array of other local civic and community groups, and significant population growth to the lake areas in and around Southmont.
