The Columbia Forest Historic District is a national historic district located at Arlington County, Virginia. It is directly east of the Virginia Heights Historic District. It contains 238 contributing buildings in a residential neighborhood in South Arlington. They were built in two phases beginning in 1942 and ending in 1945, and consist of 233 single-family dwellings contracted by the Federal government to house the families of young officers and ranking officials. They are two-story, two- and three-bay, paired brick or concrete block dwellings in the Colonial Revival-style. They were built under the direction of the Army Corps of Engineers by the Defense Housing Corporation.
