Salvo Post Office, Post office building in Salvo, North Carolina, United States

Salvo Post Office is a wood-frame building about 8 by 12 feet (2.4 by 3.7 m) standing on 2-foot pilings on the west side of North Carolina Highway 12. Its gabled roof is covered with wooden shingles, the exterior is wood-sheathed, and four 4-by-4-foot sash windows light the interior, which holds the post office lobby and the postmaster's workroom.

The structure was built in 1910 by Lafayette Douglas and gained recognition on the National Register of Historic Places in 1993. Its listing followed after the facility survived fire damage the previous year.

The building represents a postal tradition where postmasters purchased portable structures and relocated them to different locations as needed. This approach allowed small communities to maintain mail service without constructing permanent buildings.

The building stands on the west side of North Carolina Highway 12, about 0.1 miles (0.16 km) south of the intersection with Park Road. It rests on 2-foot pilings and has not served as a post office since the October 1992 fire, so it is viewed from outside only.

In 1988 the U.S. Postal Service settled a long dispute by naming the Ochopee Post Office in Florida the smallest in the country and Salvo the second-smallest. A 1970s wire-service photo had called Salvo "one of, if not the smallest in the U.S. postal system."
