The Carl Mackley Houses, also originally known as Juniata Park Housing, is a private apartment complex in the Juniata neighborhood of Philadelphia, Pennsylvania. Built in 1933-1934 as single-family apartments, it opened in 1935. The project was sponsored by the American Federation of Full-Fashioned Hosiery Workers, with financing by the Housing Division of the Public Works Administration, of which it was the first funded project. The complex was named for a striking hosiery worker killed by non-union workers during the H.C. Aberle Company strike in 1930.
