Apex is a town in Wake County, North Carolina, United States. At its southern border, Apex encompasses the community of Friendship. In 1994, the downtown area was designated a historic district, and the Apex train depot, built in 1867, is designated a Wake County landmark. The depot location marks the highest point on the old Chatham Railroad, hence the town's name. The town motto is "The Peak of Good Living". In the late 19th century, a small community developed around the railroad station.
