The Hazelwood Branch of the Carnegie Library of Pittsburgh located at 4748 Monongahela Street in the Hazelwood neighborhood of Pittsburgh, Pennsylvania, was built in 1899. It was added to the List of City of Pittsburgh historic designations on July 28, 2004. The Hazelwood Branch Carnegie Library left this location in mid 2004 and was reopened in a recently constructed building on Second Avenue. In 2009 and again in 2011, the branch was threatened with closure due to funding shortfalls within the Carnegie Library system.
