The Apex Union Depot is a historic railroad station located on Salem Street in downtown Apex, North Carolina and is the centerpiece of the Apex Historic District. Constructed in 1914 by the Seaboard Air Line Railroad, the building shared service with the Durham and Southern Railway, but now houses the Apex Visitor's Center, Apex Chamber of Commerce, and meeting rooms rented out for special events. A 37-foot (11.3 m) Louisville and Nashville Railroad caboose is located beside the building. In December 1998 the Apex Union Depot was listed on the National Register of Historic Places.
