Freedom Park is a two block long elevated linear park in the Rosslyn section of Arlington, Virginia. It was built on an elevated concrete structure originally constructed for use as an automobile overpass, and as such, rises above and over the surrounding streets.

In 2008 the Newseum moved to a new location in the District of Columbia, upon which time a property developer took over operations of the park, and most of the original exhibits were removed.Today the park is used primarily by residents and workers of Rosslyn as a quiet escape from the busy city below.
