Amerikavej ("America Road") is a street in the Vesterbro district of Copenhagen, Denmark.

John Murray Forbes, America's consul in Copenhagen, constructed a country house named Amerika at the site in the 1810s.

Theodor Christian Marstrand owned a property at Amerikavej where he both lived and operated a tool factory.

His son Jacob Marstrand grew up to become a prominent figure in local politics in Copenhagen.

The lower part was converted into a workhouse under the name Københavns Arbejdshjem or Redningshjemmet Nain in 1884.
